MTN does not reconnect my lines

Hello Peter I am one of MTN customers and I would like to lay a complaint about the company. There was a point last year where I lost my contract sim card without noticing since the sim card was always in the modem so I didn't use it on regular basis. A month down the line I received a call from MTN telling me I owe them R10000 PLUS MINUS, so I blocked the sim card immediately them I explained why I did not block it immediately after losing it. I told them that I did not know that the sim card was lost, so I asked them to investigate for me as to who the culprit is. They told me that they can not investigate until my payment is made. When I called the customer care line trying to make arrangement of payment, they told me I no longer deal with them but the legal action department and the gave me the numbers. I called the legal department as MTN gave me the number and I was told that I did not have a profile with them, I when called MTN to tell them my story they gave me another number which didn't get answered no matter how many times I tried. I then decided to pay MTN through the account number I normally use when I pay. It certainly reflected on MTN side that I payed, so they confirmed when I called to ask. I then requested that they please reconnect my lines so that I would be then able to use my sim card and cancel my contract with them. I was promised that those legal action people were going to call me. Since then I was not contacted, even though I keep on calling MTN who always tell me the same story each and every time I call. I don't need too much from MTN, I need is for them to reconnect my lines so that I can cancel my contact with them before my bill piles up again (without me using their services) .Please, Peter. Your concern will mean a lot to me. My contact number is *** YOURS SINCERELY MTHOBISI MICHAEL BLOSE
