Vodacom ***** complaint

I have been having problems with my vodacom account from inception. There were two accounts under my name which I only app**** for one, I have been reporting the matter but to no resolution till date. The only number that I am supposed to be paying for is ********** 494, I paid R1400 as I was advised that its the only amount that I have to pay to have my account up to date thereafter I can pay my monthly subscription. I have been paying that without fail. Now my account has been handed over for no reason and I am told that I am owing R7000 from VVM debt collectors. Please assist because this is truly frustrating. Why am I still paying for an account that I've never received services for>
