Horrible Service From Booking.com

Booked a trip to Zanzibar, paid a deposit to the hotel Pili Pili Sunrise, received an email last year advising that there is an over booking on my dates and the hotel won't be able to accommodate me. I have been struggling to get my deposit back since last year. Pathetic service 🙄

Won't be making use of booking.com again. They just ignore my emails ,I even sent proof of payment yet no response 😑
