MTN online contract renewal is a failure

I app**** for a contract upgrade using the online portal on the 14th June and received a confirmation email on the 16th June. Since then nothing. I spend 4 hour on the phone last week Thursday and Friday getting passed in a full circle between 135 help desk, online sales, online activation, retention department who put me back to the 135 help desk, absolutely no assistance, update or guidance. I have been to the MTN shop at Hemingway's in East London, who say they can't help me because I did the application on line, but can't tell me who can. What a useless bunch.
