Connection Error

I have been using my routers for about 7 months now the connection wasn't great but atleast I could connect with some buffering. Ever since telkom has terminated their partnership with MTN my routers are not connecting. My data is expiring with use not because I don't want but because I'm unable to connect. When I call the call centre I'm told that there will be a cancellation fee which I don't understand what for because what we agreed on initially Telkom is not upholding their end of the deal. I'm paying every month but cannot use my router because there isn't coverage where I live anymore and when I took out the contract I was told that I have coverage. I've loaded a ln investigation into the matter and it's been 2 weeks but no feedback is being provided to me and no solution is being provided to me either. So how is it that I must suffer with connection and telkom gets my money every month with no hassles.
