MTN the worst service provider

I upgraded my account in about April and since then MTN didn't debit my account, I now have been handed over to the lawyers and I was told to pay R28 000 when I contacted the legal department they told me to pay R5000 but I said I'll go to the store to get everything else sorted out as well, the lady from the legal department agreed and even sent me an email saying I made arrangements. I get to the store at Clearwater and I get told I must pay R7000 and I query what the R7000 is for and that I refuse to pay reconnection fees or anything else other than my premiums cos this is not my fault. She tells me my account is on cash and not debit order.No one could tell me what the R7000 was for and I was told to contact the legal department again to which I refused and told the store to sort it out. The store called me 2 days later with no answers or more info than what I got when I went to the store and again I'm told to pay the R7000 so they can change my status from terminated or Pre terminated. My account still haven't been paid and I will keep on refusing to pay reconnection fees or anything else. I even tried to contact the store (the person Desmond who messed up my account) where I did my upgrade but no joy in speaking to him because he doesn't answer my calls or respond to my messages. I have had this account for over 20 years and I was always on debit order because someone decided to change my account to cash now I must sit with this issue and can't get it resolved.I got a call from Sapphire Debt collectors yesterday telling me I must now pay R29 000 what a joke and they can't waiver the reconnection fees so I guess my account will never be sorted out. Also the R29 000 is the cancellation fees for my contract. I was also told if my account get sorted and I pay the R5000 I will not get compensated for my data or minutes so what will I be paying for then. If I can't get my minutes and data MTN change my balance to my subs only cos I won't pay for something I didn't receive.I guess MTN doesn't need my money. I got another call from Sapphire today. Are they going to call me everyday now? MTN if you can't sort out my contract that's fine I'll keep your phone's for free. I can get data and airtime from another service provider
