2 year contract turned 4 with excessive billing

So I had a contract with altech got an iPad which I cancelled and paid their amount. When the contract was moved to MTN after they sold to them I started getting billed again by mtn. I tried to cancel this but nothing.

I kept being debited R110 which increased to R149, with no indication as to what I am now paying for? Data or the iPad? If either? Why not inform me?

So I call to cancel the account because I see that it’s no longer active, this was in October. They tell me my account was suspended because it’s in arrears? How? When you are debiting my account monthly? Apparently I owe R3400? Based on what? Nobody tells me. Can I see the billing statement? No. So how do I trust what you are telling me?

As of today they took my money, R3400? For what MTN? Where is my billing statement? What does the R149 you have been taking cover? Is there such a thing as a lifetime contract? If there is really, Who did you sign it with???

It’s one thing to be disrespected by your call agents but what you doing borders on bullying and abuse.
