Poor service

My MTN contract was due for an upgrade on 1st July 2015. The consultant Xolani assisted us with the new contract on a Samsung S6 Edge. Due to systems down I had to return the follow day to collect the new phone. Got there he said they do not have the S6 Edge in stock, thus have to take the S6, which I did not want. He also said I was not credit worthy and do not qualify for the S6 Edge. He in the meantime did a sim swop, which I cannot use as I don't have a S6 Edge. It is day 5 and I don't have a phone nor a sim card. He has done absolutely nothing to resolve my problem or tried to located a phone for me. He said it could take upto 3 months before I could get a phone. In the meantime I am without a phone!!! I have never come across such incompetance in my life. It is a great pitty that such a person is the face of thr MTN brand. I have a second contract to upgrade, MTN = NO!!
