Priceline was advertising a super low flight cost on Google Flights. Selected the flight I wanted, chose seats, entered credit card info, and clicked purchase. Then... nothing happened. It took me back to the original flight selection fee, not telling me whether or not my card was charged or if anything happened at all. I consulted Priceline's customer service via chat. One agent told me the flight wasn't available and to find the flight somewhere else (What? Priceline is willingly giving away business?) The second agent told me it was a problem with my credit card (there's no problem with my card... in fact it worked perfectly with Expedia). Each chat agent ended the chat before I was done asking questions. I'm shocked and appalled that this Priceline conducts its customer service with such nonchalance and disregard. AVOID using Priceline at all costs. If this is how they act towards prospective customers, imagine how they'll treat you once they have your money and have nothing to lose...
