Refund - Consumer Complaint for Bradlows - Head Office

I have been waiting for a refund for delivery (R520) which I did not use the services. I have given all docs asked of me, copy of ID & bank statement on the 30th of Sep 2020. I've been calling the store & speaking to the manager (Solly). He has been so rude & not helpful, telling different stories which do not make sense. I am fed up because he does not call me back instead tells me about Head Office delaying. Please Help.
