Distasteful and horrible customer service

I have experienced a horrible customer with Capitec Bank.On the 2nd of November 2024 they debited an mount that was not agreed upon, I called their call center and I was instructed to go to the nearest branch, at the branch I was told it'll take 48 hrs for the reversal to be processed. On 5th of November I called the call center to ask what's the delay and they said they don't know, then I received an email telling me that they're investigating and they will call me in 2 hrs and that as well didn't happen. I'm very disgusted with their customer service and I need all my premiums back.
