Shockingly horrible email correspondence

Unfriendly Email correspondence. Did a booking via booking.com and never received a welcome email / deposit request. Was informed the next day that my booking had been canceled due to lack of payment. I immediately emailed the establishment and ask for such details. No response. In the mean whle I booked the room again. I receive an email the next day again telling me that the booking had been canceled. I repeat my response and suddenly I receive a response. The lack of understanding or willingness to assist was astonishing. Although I mentioned that I had received no welcome email nor a reply on my first request for banking details I received extremely unfriendly responses whereby I was blamed for the loss in booking. Conveniently Gavin decided to trust booking.com when it suits him but when I say I responded to the establishment via the app, his only response is "this matter is now closed". Although not expressed in those words, the message Gavin sent me was basically "**** you". He wouldn't even make a minimal gesture of apologizing for the establishments failure to respond to my first request. Well done on the customer service Gavin and willingness to assist.
