No one can help me

Hi, please can someone assist me. No one via the phone can help me. I app**** for an overdraft of R75,000 it was approved with reference ***, I am trying to accept it online and it gives an error. No one on the phone can help me - internet banking queries/transactional lending. I want to accept it so that I can move forward with the cheque account. I have also signed acceptance of credit card application *** and to date haven't heard anything. Guys, please can someone sort this out for me. Many thanks, Ivor
