Paying for DSTV that I dont have?

I used to have a DSTV premium package. I cancelled it earlier this year. On the 21/11/2022 i was debited R280.28 by DSTV. I called on the 21/11/2022 at 08h09 and spoke to Tammy. She said she sees the debit and she will reverses it and the money will be back in my account within 72 hours. On the 05/12/2022 i called again because i had not received my money back. I spoke to Pearl who asked if i can go to the bank to reverse the money. I told Peral that i can not. Pearl then put me on hold. When some one spoke to me again after being on hold, it was Steven this time. I explained the whole problem all over again to Steven. He said he will call me back because i had been on the line for 33 minutes to try and get my money back. Steven did call me back and told me that i will receive the refund within 72 hours from the 05/12/2022. It is now alot longer than 72 hours and i still do not have my money back.

What do i need to do to get my money back.? I am not using your services, so why are you taking my money?
