MTN POOR SERVICE

I took out 3 new contracts at MTN Centurion Mall on 2nd May 2019. The one number's contract has not been correctly loaded since inception. In trying to rectify the contract package issue, MTN has now totally disabled the number and does not seem to be able to rectify their error. The consequence is that for 1 week now, my wife has been without any service. Nobody can phone her, and she can't phone or contact anyone, or use anything on her phone. This puts her at risk if there is any type of emergency, and I will hold MTN legally and financially accountable should anything happen to my wife as a result of their negligence. I am really disappointed in MTN's service and apparent lack of s****s/knowledge in their own systems. I have tried multiple channels to try and get this resolved, without any progress. If this is not resolved in the next 24 hours, I will be returning the phones and cancelling my contract, as MTN is currently in breach of contract.
