Next level lack of service

Due to bad service and often receiving wrong information from the customer service desk (at several branches), I finally decided to move. I closed my credit card in the branch. All they did was dial a number and gave me the handset. I had to do it over the phone. Afterwards I asked if I could just call to close my current account as well and they said yes.

A few month later, after ensuring that all my debit orders have been moved I finally called, and thought my account closed.

Months later I get a call from vericred. My account is in arrears due to unpaid banking fees and I have been handed over. During all this time (18 months) ABSA never tried to get the money themselves, nor was I informed that I have been handed over. All this time I was blissfully unaware that I owed any money and now my credit rating is suffering because of this.

Whether or not I owe the money is irrelevant, I expect one should be notified of handover. This is ridiculous service and I expect my credit score to be restored.
