I used Kayak.com to buy plane tickets
I used Kayak.com to buy plane tickets, which sent me to Underpricer. Immediately upon buying the tickets I started getting phone calls telling me that my "tickets were not guaranteed" unless I paid more money. I told them that if they've sold me on just the idea of a ticket, and not an actual ticket, then refund my money immediately. We argued, but they eventually said they would do that. They didn't, I refused the charge on my CC, the CC company eventually charged me anyway, and Underpricer still didn't cancel that ticket because I kept getting alerts to get on that flight. In complaining to Underpricer, they insist that it's my fault and that the most they can do is refund the fees. This company is using deceptive practices and harassing people, and the company needs to be banned from Kayak and from doing business in the US.
