Cancelation of Booking

I'm so disappointed about Pavillion Hotel, Durban. Last year of 2020 I booked my vacation with them early in February. I paid the deposit for my booking. I was booking for 18 - 24 Dec 2020. Unfortunately in March 2020 we had an outbreak of Covid-19, which shut the doors of many businesses to date. I then canceled my booking with Pavillion Hotel due to the shut down. I've been communicating with the staff at the hotel about my cancelation, and we agreed about my refund. They always promise to refund me but until today nothing happened. I just don't know what else should I do. It seems like the staff at Pavillion Hotel are deliberately ignoring my request for a refund. I need my money back, and so disappointed about their dishonesty. I won't encourage anybody to go to Pavillion hotel, Durban. They don't have any respect for their clients. I'm Simon from Gauteng. ***
