Refund:Accomodation

I am struggling to get my refund for accomodation reservation due to Covid 19. I was supposed to have received my refund in March 2020, after many phone calls & emails back & forth with no response. The refund was agreed upon with the front desk supervisor/manageress, this is so unfair because the cancellation was due to something beyond my control & I'm being given the run around. My next step would be to lodge a complaint with the Tourism Board of SA & Consumer Watch Ombudsmen. This kind of behaviour from a reputable hotel group like the Radisson is unacceptable.
