CAPITEC COMPLAINTS - BAD SERVICE

I have tried changing my debit order details with Capitec numerous times, their system gives an error as per the Consultants. Due to this my debit orders are not enforced and I have to inconveniently go into the bank to pay my loan account. Due to this, Capitec has now listed me as a bad payer according to their SMS's, which is not my fault?! I have sent countless emails to their customer care as they don't give you a complaints department, I have spoken to so many different consultants which they do not give me feedback, and up to date the issue is still not resolved, which means my debit order will not be enforced AGAIN this month and my credit score has now been affected. I am at this stage considering implicating the Ombudsman.
