Refund owed and non responsiveness

I booked and paid the deposit for my stay at the Imperial Hotel in Pietermaritzburg (Part of the Misty Blue group) for 13 June 2021. Due to the cancellation of the Comrades marathon I had to cancel my booking. I informed the hotel of this on the 11th of February 2021. On the same day I was asked for banking details for the refund to be processed. I submitted these immediately. 4 and a half months later, approximately 25 emails and 20 phone calls, I have still not received my refund. I have been sent from one person to the next, but no one gets back to me. I've left more messages to be called back than I care to remember (No one is ever available to take a call).

I was told that I need to speak to Michelle Davids but can not contact her by phone. She ignores ALL emails and I have not ONCE heard from her.

I was given the email address of the GM and CEO, none of these yielded any success either.

I'm at a loss at to what to do. I understand that the Hotel industry is under pressure but treating your customers like dirt won't help the industry recover one bit. Common courtesy would be to in the very least respond to the client and acknowledge the problem so a solution can be agreed on jointly.
