Edgars...RMCS

I had an account with Edgars and cancelled years ago.I still receive airtime from RMCS even though Iv told them to cancel the subscription.Im trying to do a sim swop and I'm told RMCS changed my number from prepaid to Contract and that was done without my consent.Iv been calling with no assistance.Im still trying to understand why Edgars would give of my personal information and allow RMCS to do this without my consent.Please fix this because I don't want this RMCS thing and I want my number back.
