I booked a flight through Booking.com but entered my email address incorrectly. I realised something was wrong and contacted their customer service a month before my flight, providing my Payment ID and Acquirer Reference Number.Despite this, I received only automated replies telling me to call phone numbers where I was asked for a booking reference I didn’t have. I sent multiple emails explaining the situation but got no real help.Finally, I escalated to their CEO. A staff member named Renato found the issue — a simple typo — in one minute. Why couldn’t customer service do that during the 30 days I asked for help?To make matters worse, Booking.com isn’t part of any UK ombudsman or ADR scheme, This means that when something goes wrong, UK customers are left with no access to an independent complaints process. Booking.com is not listed on Resolver, and because of Brexit, UK residents can’t use the EU’s ODR platform either.Very disappointing service for such a well-known company.
