Santana unit 607

Unit 607 Santana Margate I booked my family, through booking.com with Santana in margate, the service was an absolute horror, its now gone 5 months and did not recieve my deposit back, booking.com did not come to the party and assist in getting my deposit back, and the company that owns the unit, Ogatsheni Architecture and engineering does not come back to you or even reply to your messages, its sad that these people are getting away with things like this,
