MTN Accounts/Legal useless

I have several lines with MTN which some have expired (years ago).

I lapsed on payment years ago resulting in my account being handed over. For the last 3-5 years I have been paying monthly installments by debit order to VVM.

I am paying for expired contracts which is why my balance keeps accumulating when its suppose to decrease. I have tried to call and cancel contracts to avoid being billed for service s not used.

I have called MTN several times, been sent from pillar to post, from customer care, to accounts to legal but not getting resolution.

Its unfair that I should be paying for expired contracts. My balance outstanding is escalating, its unfair business practice. I am tired of calling MTN and not getting any solid feedback nor solution to this issue.

The level of customer service aid atrocious and ridiculous. I am considering going to the ambud/legal route in the attempt to get some form of resolution and fairness.

I regret the day I took out MTN contracts for my family!!!!
