Transfer of my prepaid to a contract

<p>I have been using my vodacom number as a prepaid number since 2012, only last year I tried to transfer airtime and the system wouldn't allow me, I then called vodacom to findout what was the problem, it was then explained to me that my phone number is under a contract with RMCS, which I was not aware and I never entered into any contract with such a company, I was then told to call some 086 number to have my number removed from contract, which I did three times, up to date nothin has changed and vodacom does not wanna help me on this whereas I have explained that I never enter into any contract with RMCS, I need help regarding my number as soon as possible </p>
