Bad service with securing a contract

I recently app**** for an I-phone 6 contract with MTN. A lady (I think it is Charne) was helping me. I submitted all the required documents, and she confirmed that all my documents were appropriate and accurate. She asked me to wait in the mall, as my contract was likely to be approved within a few hours. I then left the mall after waiting to 5 hours. Later that day I received an SMS from the vetting department who indicated that my payslip was not clear. I immediately called Charne, to tell her about my SMS. She said that I should go back to the branch to resubmit the payslip. I couldn't do this as I didn't have a car at that moment. I didn't see the reason why I was supposed to anyway, because it was not my fault that she didn't scan the pay slip properly. I submitted an original copy as far as I was concerned. she then said that she would send me her email address via SMS, for me to scan the payslip and send to her. I have not received any communication from her since then.<br> <br> I sent a complaint email to MTN customer services, and have not received a single response. I am dissappointed by the services I received. It is really sad to see how many people are complaining about MTN.
