I tried to pay for a vacation rental last night through "Pay Now"/Flip Key on TripAdvisor site and each time I submitted my info (i.e. address, credit card number. etc), it would come back and highlight a box that said I didn't put the information in correctly. The box highlighted was blank, so I assumed I had written something incorrectly, and therefore inputted my info again and clicked submit. My credit card has now been charged 3 times, yet the property owner does not see any record of me trying to pay. This is absolutely ridiculous. I will be contacting FlipKey as well as the Better Business Bureau and Attorney General's office in my state. This is certainly a scam, and there are many posts on TripAdvisor indicating that the same things have happened in the past! Why hasn't this been something that has been fixed? There are posts going all the way back to 2011 indicating that similar things have happened when people have tried to pay rentals via FlipKey. This is absolutely unacceptable!
