I booked a flight through Trip.com, but they didn't book it. Upon not receiving the tickets, I was awoken to a call from one of their representatives claiming the airline had cancelled the flight and was asking my permission to cancel my booking. Something seemed fishy so I denied and called the airline - and they confirmed the flight was not cancelled. Over the next day, I went back and forth with them as various representatives came up with contradictory lies for why I didn't have tickets (they're still processing - you'll get them, the flight is cancelled, there was a problem with the airline not processing them, etc). Despite claiming that they would resolve the issue, they refused to book me new tickets for my original flight (or a comparative flight on the same day) because the ticket prices had increased since my original purchase. Ultimately, by the end of many back and forth calls (receiving the last at 2am while I was sleeping - again!) they told me they "could not" book my original ticket and I'd either have to change days to a cheaper flight (which I told them from the beginning was not possible) or cancel my booking and rebook at the new ticket prices (for which they would "compensate" me $27 - although new ticket prices were $150 greater than my original $106 flight. (I have not yet received the refund and have seen many reviews that Trip.com will keep it at "Pending" forever - so I suspect I may have to dispute the charge with my credit card company.) As they weren't willing to solve the problem, I did - by rebooking at the new, inflated prices with a different provider. I had no issue with the other provider - and received my ticket confirmation immediately. Lastly, when I went did Trip.com's internal feedback survey, it would not let me submit a negative review! The "Submit" button didn't work - across many browsers!
