In early May 2019 I rented an apartment on Booking.com for 1000 euro on a non-cancellable and non-refundable basis. Shortly after, Booking.com unilaterally canceled my reservation without first asking me, thereby violating my agreement with the rentor. Initially, they claimed the apartment was no longer available for rent but then they changed their story and wrote that the apartment owner was taking credit card numbers to engage in fraud. They did not provide any proof of this allegation. In France visa cards are debit cards so the 1000 euro amount was immediately taken out of my account. Booking.com is refusing to take any responsibility and is asking that I work it out with my bank (after initially asking me to work it out with the allegedly defrauding apartment owner!). My bank is stating that I must sign an affidavit that I did not voluntarily provide my credit card number - which I obviously cannot sign I did voluntarily provide my credit card number since that is a Booking.com requirement. Booking.com has provided no proof of their allegations, they are not reading any of the documents I submitted showing that I cannot honestly sign the affidavit and are simply giving me the run around. They are gambling that customers will not sue them for a 1000 euro loss and will just give up. Throughout the many exchanges they have consistently misrepresented what they would do to help. At one point they wrote that if I provided proof that the money was charged to my account they would reimburse me - I provided it the same day but they ignored the documents and again stated that I should work with my bank. A despicable bunch. Find an alternative if you can.
