I had been a booking.com customer since 2013. Recently I noticed that a flight booking had been made on my account under a strange name using my accumulated reward points. I tried to cancel it, but was not successful. I contacted customer service online, but they did not resolve the issue after several attempts. The last attempt I made the customer service agent actual instructed me to contact someone at Booking.com after I had them called them on the number listed on the Booking.com website. When I told them I was doing that they said they would expedite my issue and someone would contact me in a few days. That was 2 months ago and I did not hear anything further from them; the issue did not get explained or resolved. I have now deleted my account, and I will not be doing business with Booking.com in future. I would urge everyone else reading this to do the same.
