Nightmare experience

Absolute nightmare with terrible customer support. They listed a booking that should have been removed as requested by owners multiple times. The booking was confirmed, payment processed. When I arrived the owners were unaware and said they had requested multiple times to remove the listing and that they had not confirmed the stay. It has now taken two week to get resolution. They offered a measly $68 refund, even though I had hundreds of dollars additional payment to get another hotel when arriving. I made the booking three months in advance and the prices shot up. This company does not stand behind their service. It is also impossible to actually speak to someone. Customer support is pathetic, 24 hours for a message reply and without any direction or clarity. This is not how I want to spend my time off, sorting out booking.com ***** ups.
