Hello and apologies in advance for the length but I don't want to leave anything out. Last year on July 10th I booked and paid for a holiday (UK caravan park, South Wales) to take place during half term this year. I checked my account on Booking.com yesterday to double check the dates to book my annual leave and my booking has not been cancelled but deleted altogether. There is no proof of its existence and I was never sent a confirmation email, I have spent 11hrs checking all email accounts, my bank account, my search history and even screenshots of the booking to no avail. My bank has verified that I did pay the money to Booking.com but as the transaction is older than 120 days they can't help, they gave me details for Citizens Advice Burea who told me to raise a complaint with Booking.com but I have a string of 12 emails from them saying they can't help without a booking number or they send me their automated phone number for customer services which only helps people with confirmation numbers. I sent a complaint to them and tried raising a dispute but every email is the same: confirmation number. The financial ombudsman can't help, my bank can't help and Booking.com won't speak to me. Please please someone help as I've lost a £542 holiday and I'm about to lose my job so it was the one thing we had left to look forward to. Thank you.
