A brilliant bank who also have a mobile phone division. I aa client for banking and phone I have a problem with the answering where messages are left. When idial 132 I am prompted to insert my peronal Identity no. I hve tried but not accepted and I cannot pick upy messages. I phoned Capetec ND they tried to fix the problem buto no avail. I called at Capitec and a very helpful man made cas to get it rectified but again to no avail. He said he would continue trying. Please can I have my message receiver fixed!
