Disgusted with MTN

I am sick an tired of MTN. I have battled for close to 4 months to cancel my expired contract which ended and I did not want to renew. They are still deducting and I phone them on *** and speak to reception she transfers me to automative machine and then I get cut off. Then I call again and then it says the number you have dialed does not exist. Please MTN sort this out. Caren ***
