1. Before you complain: what to prepare

Booking.com customer service handles thousands of complaints daily. The ones that get resolved fastest have clear evidence and a specific ask. Before you contact them, gather:

• Booking reference number: the confirmation number from your booking email.
• Photos: if the issue is property condition (cleanliness, damage, missing amenities), take photos immediately. Timestamped photos from your phone are ideal.
• Screenshots: if the issue is a pricing discrepancy or listing inaccuracy, screenshot the original listing description and the reality.
• Timeline: note when you arrived, when you discovered the issue, and when you first reported it.
• What you want: a refund, a rebooking, a partial credit, or an apology. Be specific.

Vague complaints ("the room was bad") get vague responses. Specific complaints with evidence ("the bathroom had mould on the ceiling, here are three photos, I reported it at check-in") get results.

2. How to file a complaint through Booking.com

2.1 Through the app (fastest)

1. Open the Booking.com app and go to "Trips" or "Bookings".
2. Select the reservation with the issue.
3. Tap "Help" or "Contact us".
4. Choose the category that matches your complaint (property condition, cancellation, refund, etc.).
5. Describe the issue clearly and attach photos if relevant.
6. Submit. You will receive a case number.

2.2 Through the website

1. Log in to Booking.com and go to "My Bookings".
2. Click on the reservation.
3. Click "Help with this booking" or navigate to the Help Centre.
4. Follow the prompts to describe your issue and submit.

2.3 By phone

Booking.com has a customer service phone line. The number is shown in your booking confirmation email and in the app under Help. Phone support is available 24/7 but wait times vary. Having your booking reference ready speeds up the call significantly.

2.4 What NOT to do

Do not email a generic Booking.com address. Do not complain only to the property owner without also logging it with Booking.com. If it is not logged in their system, it does not exist for dispute purposes.

3. Common complaint types and what to expect

3.1 Property not as described

If the property differs materially from the listing (wrong room type, missing amenities, cleanliness issues), report it to Booking.com before checking out. They may offer to rebook you nearby or process a partial refund. Reporting after checkout weakens your case.

3.2 Cancellation and refund disputes

If you cancelled within the free cancellation window and have not received a refund, contact Booking.com with your cancellation confirmation. Refunds typically take 5-15 business days depending on your payment method. For the full refund timeline, see our guide to Booking.com refunds.

3.3 Overcharging or hidden fees

If you were charged more than the listed price, or the property charged fees not mentioned in the listing (cleaning fee, city tax not disclosed), screenshot the original listing and your payment receipt. Booking.com can mediate and issue credits.

3.4 Host behaviour

Rude or unresponsive hosts, safety concerns, or harassment should be reported to Booking.com immediately. These are taken seriously and can result in the property being removed from the platform.

3.5 Technical issues

Payment processing errors, app glitches, or booking confirmations not appearing should be reported through the Help Centre. Include screenshots of any error messages.

4. How to escalate if your complaint is not resolved

If Booking.com's initial response does not resolve your issue, you have several escalation options.

4.1 Request escalation within Booking.com

Reply to your case and explicitly ask for it to be escalated to a senior agent or manager. Use the phrase "I would like to escalate this complaint." This triggers a different review process in most cases.

4.2 Social media

Booking.com monitors their social media channels (X/Twitter, Facebook). A clear, factual public complaint with your booking reference often gets a faster response than the standard support queue. Do not be aggressive. State the facts and what resolution you want.

4.3 Chargeback through your bank

If Booking.com cannot or will not resolve a legitimate dispute, you can request a chargeback through your credit card provider. This is a formal dispute process. You will need evidence that the charge was not in line with what you agreed to (listing screenshots, photos, communication records). Chargebacks should be a last resort after exhausting Booking.com's own process.

4.4 European Consumer Centre (ECC)

For cross-border complaints within the EU/EEA, you can contact your national European Consumer Centre for free advice and mediation. Booking.com is based in the Netherlands, so complaints from EU travellers have this additional avenue.

5. Tips for getting a better outcome

• Report during your stay, not after. Complaints lodged while you are still at the property carry more weight and give Booking.com options (rebooking, partial refund).
• Be specific and factual. "The listing said sea view, the room faced a car park" beats "the room was disappointing".
• Keep all communication on-platform. Messages through Booking.com's system are documented. Phone calls and side conversations are not.
• Follow up within 48 hours. If you do not hear back, chase. Cases that go quiet get deprioritised.
• Know what you want. A full refund, a partial refund, a rebooking, or a credit for a future stay. State it clearly.

6. FAQ

How do I complain to Booking.com?

Through the app (Trips, select booking, tap Help) or the website (My Bookings, Help with this booking). You can also call their 24/7 customer service line. Always log the complaint in their system, not just with the property owner.

How long does Booking.com take to respond to complaints?

Initial response is usually within 24-48 hours for app and website complaints. Complex cases (refund disputes, property condition claims) may take 5-10 business days to resolve fully. Chase if you do not hear back within 48 hours.

Can I get a refund through a Booking.com complaint?

Yes, if your complaint is valid and supported by evidence. Refunds for property condition issues are typically partial. Refunds for cancellations within the free cancellation window should be full. See our guide to Booking.com refunds for the detailed timeline.

What if Booking.com ignores my complaint?

Request escalation to a senior agent. If that fails, try social media (X/Twitter, Facebook) with a factual public post. As a last resort, request a chargeback through your credit card provider with supporting evidence.

Can I complain about a Booking.com property after checkout?

Yes, but complaints made during your stay are much more effective. After checkout, Booking.com has fewer options (they cannot rebook you or inspect the property). If you must complain after checkout, provide timestamped photos taken during your stay as evidence.

This guide is general information based on Booking.com's standard complaint processes. Individual outcomes vary. Always log complaints through Booking.com's official channels for the best chance of resolution.
