Non existant service

I have been sitting with no cell coverage for 3 weeks now. I have tried calling 135 but I cannot get through to a human being to assist. I have gone into the MTN shop and I was told that MTN had changed systems and that my payment hadn't been allocated because my account numbers have changed. I then took POP to the MTN shop so that it could be allocated and I was told that I just have to wait because they are extremely busy with these requests. This was 10 days ago. I still cannot get through to anyone. I still do not receive a statement. I still cannot see anything on MYMtn to try and sort this out. I am now at my wits end and I have to say that this is the worst service Ihave ever received from MTN. At this stage i think it is fair to say that I am being ****** because I am going to be responsible for payment of these 3 weeks even though i had absolutely no control over this situation. It is ****************.
