MTN Cannot activate contract

*** ***

I've entered into a new cell contract with MTN six weeks ago. The phone has not been activated since. The emails I have sent were unanswered. I phoned the call center I visited the stores at Northcliff, Randridge and Brigh****er Commons. Each time I have to speak to the call center and each time I am told that it will take up to 24 hrs for the sim to activate. I have now left my phone with Queenie at Brigh****er Commons Please cancel my contract and reimburse me for expenses including a cell phone cover and screen protector.
