2 months No updates or refund

Etienne from N1city Telkom management has taken 2 months to tell me why my wifes contract was done as new and not upgrade, we have been charged for 2 contracts plus all over usage gets double charge instead of just on one number. I have been told he will have an answer but still nothing and only partial refund. We are still owed another R700. This is my 6th Telkom post in a year on my contract, my landline and wifes contract this is a joke
