Capitec won't open a new acc

After being with capitec Bank for 8 years I wanted to close and re-open a new account due to an unauthorized debit order every month. Capitec told me that I can't reopen an account due to ***** that took place e in 2013 and the account was closed to my surprise I was still using the account to this day and no one has ever contacted me for anything so as a result I'm being investigated for something I know nothing about I tried calling the forensic but still no one had answers to my questions
