NO SUPPORT FROM ABSA NO RESOLUTION FROM ABSA

I have been banking with ABSA for years. I recently decided to close my accounts because of high interest charges and not being able to cope with credit card payments and interest charges that were killing me. From there I went onto Debt review and paid up all outstanding monies much faster than anticipated. ABSA has however not stopped sending me notifications about new credit cards after I asked them to CLOSE my accounts. Paid up letters have been sent to them and generated by them but I'm still getting bombarded with sms's which clearly means my data has not been updated on their side. When I tried calling the Debt Review department to solve the issue there is always some reason why they can't get it done once and for all. Today's reason was that I didn't pass security questions - a new one. I'm at my wits end.
