Pay as U Go switched to a Contract without any con

On Sunday 29/02/2016 at 13h00, i received a sms from Vodacom congratulating me on my Flexi 55 Contract and will be debited in 48h. It was by a marketing company RMCS who works on commission. In the next hour my airtime of R210 and 3GB and 160 points was erased from my phone and had no excess to my anything, my phone was locked. I was NEVER aproched for a Contract by any of the two above companies. I phoned Vodacom and was told they have problems with RMCS and cant do anything to switch my phone back to payg. I was issued with a complaint number, Vodacom would call me back in 48 hours, and apologised. I have NEVER heard from any of the two companies yet. I am still with a locked simcard and ****** of my money and GB's. Sad to say BYE BYE VODACOM after feeding your company with cash every month for over Twenty Years!!!!
