my life is a living HELL

I am so frustrated with MTN. They made my life a living hell since i upgraded my contract in 2016 Oct. Incorrect Billing, i don't even know how much am i supposed to pay because the instalmennt we agreed on, was never there, it was always more and i am sick and tired of all this. They said i owed a huge amount, they have listed me as a bad payer, i do pay every month and every time when i call the call centre, my account is blocked and no one knows anything, however i get my statement each month, different amounts i get and the agents are very rude and telling me where to get off.

All i want to do is to TERMINATE my contract, no one cannot help me on that and they keep STALLING.

They keep on saying they sending email to whoever and i never get a feedback, when i call every time, i get a different story.

PLEASE HELP ME, I WANT TO TERMINATE MY CONTRACT WITH MTN, PAY WHATEVER CANCELLATION FEE AND ALSO IF THEY CAN UPDATE ON THEIR SIDE THAT I AM NO LONGER OWING THEM PLEASE.

Your Help will be much appreciated
