From prepaid to contract without authorization!!!!!!!!!!!!

<p>On 19th of September 2016 I received an SMS I assumed it was from Vodacom telling me I can receive free airtime of R55 every month by replying yes. So I did. On the 28th of September 2016 I received the R55 free airtime. Then my BIS stopped working. On 29th of September 2016 I called Vodacom customer service informing them of my problem. The operator told me a company by the name of RMCS that is affiliated with Jet and Edgar's has changed me to a contract account. I have no accounts with RMCS nor did I authorize a change from prepaid to contract. Vodacom gave me RMCS customer service number ********** 011, as there is nothing they can do to change me back to prepaid only RMCS can now help me. I've called numerous times and nobody answers the line. All I get is music and waisted airtime hanging on. I am now ****ed off at RMCS for acting without authorization. I need for somebody either from Vodacom or RMCS to fix this issue. I need my phone for work and without WhatsApp, bbm and Facebook I'm *****ed.</p>
