Helpless client

I'm not pleased with the service I got form UbAnk in Rustenburg. My little brother is receiving grant,everything was going well whilst he was receiving his SRD via post office until last year August, when he registered his account with Ubank. Sassa is paying the money but Ubank is giving us problems. Went to the branch and spoke to the branch manager almost the whole month nothing is happening all they tell us is that the branch code was wrong but account number it's right. But the money is there why can't they just pay my brother. Now the branch manager SHE is giving us attitude not answering our calls I don't understand what kind of service is this. Why is it taking so long just to resolve the matter!! How do we trust them with our money whilst they act like ****** so much for Good service!
