African Bank's pathetic service,no feeedback

I have contacted African bank via phone and e-mail in order to get the settlement amount on a loan account, after numerous phone calls and e-mails to the call centre and collections department , they all promise to call or e-mail back since 08/02/2016 , to this day, even the so-called supervisors don't bother to respond to e-mails and phone calls. They have now handed my account over to two attorneys, which is not legal. I paid them R10 528.77 on 03/02/2015 but this has not been updated despite me sending proof of payment to the supervisors Thabang Maponya and Nhlanhla Ntuli. They are quick to hand the client over to lawyers but a simple thing like resolving a client's query and providing feedback is not possible for them. What pathetic customer service, disappointing and costing me money for phone calls is just not funny.
