Refund Nightmare

I purchased a sound bar from Pick N Pay ( Ferndale on Republic) on the 18/12/22. Upon connecting the item, we discovered the sound quality was horrible and decided to return the item on the same day. The manager on duty decided to do a refund into my debit card that was used to purchase the item. No explanation was given as to a time frame in which the refund would clear into my account. Please bear in mind that I did ask for the option of me receiving cash to which he said no. I called the store a few days later and spoke to another manager and she advised that refunds are not done into debit cards because of the the fact that it takes 10 business days to clear which was not explained to me initially. She also said that because of the public holidays, it would affect the time frame in which the money would reflect. Fast foward to the 5/1/2023, I still have not received my refund. It is now 11 business days. Everytime I call the store they say it's a delay from the bank. This is unacceptable and unfair because the funds went off my account immediately when the purchase was done and I am waiting indefinitely for my refund. I have been patient and waited the 10 business days but it has now exceeded the time frame and still my refund has not been done.
