Absa bad service

I had an account with Absa and I used my account as a saving account, I had money in my account and a purchase went through while I was asleep and I called the Absa ***** line but they were of no help, they told me to go to the branch and absa refused to return my money..

Then a few months later the R99 ***** started happening in my account and I had to keep on going to the branch to reverse it and I was charged R40 for every reversal, I decided I'll close off the account before it became 0 but the consultant at Absa Chris Hani crossing refused and said they still investigating the ***** but my account ended up in minus and I was handed over and I have told multiple people this story and all of them keep insisting I pay money that I didn't even use, money that came out because of the R99 ***** and left my account in -
