Mtn call center zero service

I have a mtn contract and I can't call mtn. Everytime I need assistance i struggle cause i have to ask people for their phones. As I'm typing this I'm on a call waiting on mtn on someones phone who is telling me to be quick with all the waiting times at the call center. Why am I paying for service where I can't even get assistance. I've queried this twice. 1st time the guy said nothing is wrong. Second time I was told to remove my Sim and insert it again and I'm still having the same issue. I see no reason of renewing my contract if this is the **** treatment mtn gives their clients.
