Very dissatisfied

Good day After numerous phone calls ,emails I have no choice to report RMCS They activated a contract on my number in 2019 for which I never gave permission, since last year I have been phoning and sending emails to get my number back to prepaid . Last week I send Vodacom a email spoke to a supervisor was told it would be done within 48 hours. But my number is still on contract with RMCS, I need to do a simswop, can't do it as I need permission from RMCS, spoke to Phindi on Wednesday got a reference number but came Friday morning they recharged me again. As I see it either they release my number and convert it to prepaid like it was or I report RMCS and Vodacom to icassa as RMCS is a service provider for Vodacom it is there duty to sort this out.
