I demand a Full Refund!!!

We booked a place 'dream of kendwa beach villa' in zanzibar on booking.com. We arrived at the place at about 7pm just to find it was not a beach villa, infact it was more than a kilometer inland. The area was ***** we decided it would be best to find another place as it was not as advertised on booking.com.

We had to book another place on short notice eating more than half our spending money... we tried to contact the owner of the villa but he was apparently in a meeting for the whole duration of our holiday(2 weeks). We then contacted booking.com to try and get a refund as the location was not as advertised on the 'trustworthy' booking.com website. They offered us 25$ and basically said thats it. I sent them proof of the location with photos and videos, but they basically said I'm a lier. Booking.com/Dream of kendwa beach villas ows us $300 that they stole from us because of false adverti*****ts!!
