No Help

I cancelled my 1GB bolt on last year sometime. I had called in the call Centre and they said it was done. Little did I know I was still going to be charged for it and if I didn't pay I would get a threatening sms of suspension. I paid. Some months I would receive it. Others I wouldn't. I emailed customer service. I have DMd MTN in fb. But I am still suspended and getting smses to pay for something I have not received. Somebody do something. I can't beg for a company I'm paying to do their jobs. How am I to do my job without my phone? I need to call clients? Now my job is at risk because someone didn't do theirs and cancel the bolt on like I asked? This is ridiculous. What do I have to do to get someone to help? I called. I emailed. Got told to go to a store. Inboxed on fb and now I must come to hello Peter??? I'm disappointed in MTN. I wanted to cancel. And I'm sure there is a record of that. But thought to give u guys another chance. But after this. I will definitely be porting. Cancel the bolt on. Unsuspended me. Credit for the months I didn't receive. And DO NOT mix it with the months a bought a Gig via prepaid banking.
