Booked a rental for the Month of March in Florida, on the beach. Paid in advance and received multiple emails confirming the rental and hyping how wonderful it would be. Arrived in Florida and attempted to get access info from the local property manager. They informed me that the unit I rented wasn't available but they just happened to have another nearby (not on the beach) that they could let me have instead. I had a car paid for the month and return flight at the end of the month. I was stuck and they knew it.
I notified FlipKey immediately and got emails and calls that I couldn't respond to. Punch line from FlipKey was that since I spent a night in the alternate unit, it negated the Payment Protection.
FlipKey's position that it was the property manager's fault and the property manager blamed FlipKey. Eventually FlipKey offered me a 10% refund. When I attempted to accept, FlipKey acted like they'd never heard of me and, by email, asked me to open a complaint file. They're brutal and wore me down.
Avoid them like the plague. Honesty is not in their vocabulary.
