Prepaid cellphone no CHANGED over to contract

On Monday 29 Feb. 2016 my Cellphone Prepaid number suddenly couldn't go on the internet which I USE for my business email is off, I can't send SMS messages only to certain numbers and when someone phones my number ALL of the numbers show up as Private Number. I phoned Vodacom, they can't help me and gave me the number for this RMCS. I spoke to a lady RUTH and got a Ref no. she said she has sent an email to Vodacom to change my no back to prepaid and a consultant will phone me back in 48 working hours. I am still waiting. I'm super frustrated and quite angry as I have never signed up for this stupid contract but best of all is I don't have ANY accounts like Edgars or Jet or whatever else on my name! Who do these people think they are. My prepaid Vodacom number inserted in my Cellphone with prepaid Internet miraciously by itself switched over to a Uchoose Flexi 55 contract without my consent and as a customer who has been with Vodacom since 1997 and now not able to receive any help regarding this issue is going to drive me completly Crazy and I expect some sort of help here seeing that this is not my doing at all. <br> Terrible, horrible, disgusting VC and RM <br> I have also opened a Case.
