Bad service at HAPPY RHINO HOTEL IN CAPE TOWN

My name is Rolivhuwa Dangale , I booked the happy rhino hotel from the 21st of September checking out 24th of September , me and my partner when we arrived on Friday the 21st we were told that the hotel was fully booked and we can't get accommodation on how that happened I wish I knew because we booked in advance and paid fully . On the very same Friday we were forced to find accommodation because Happy rhino couldn't provide a room for us . We slept at check inn hotel were we paid R730.00 which we didn't plan . On the 22nd of September we were promised to get the refund back because it was not our fault that your hotel was fully . I tired to send emails and call the management even today I still don't have the respond
