Store Refund not reflecting in my account!!!

I returned items at your Somerset Living branch on 01/04/2023. The refund was suppose to be cash,however, they did not have any cash and asked if they can return to my credit card. I was told that it will take 2 to 3 days to clear into my account. I explained that I am immigrating and my bank account will have to be closed soon. I was assured that it will be cleared by then. It's been two weeks and the funds are still not cleared. @home this is theft. On my side, fnb is unable to pick up any credits from you. I've been to the branch again and made numerous calls to your customer care centre. I've been told by your branch that they are trying to get answers from head office and have not been successful so far. You are costing me financially and impacting my immigration process. Fix this today !!!!
