RMCS - bad service

I attempted to do a sim swap on or about 8th of April 2019 and Vodacom informed me that I have a contract with RMCS, of which I didn't ask for whatsover. I phoned RMCS on the 11 April 2019 and I was told to wait for 24 hours, after 30 hours i called them and i was told to put my swim card it shows as activated but it wasnt workin the on the 16 April 2019 i phoned them again and they told me they will escalated this matter and i received their sms saying my query has been lodged. Today i phoned them again they will escalate it. RMCS i really need my number back i need to pay my debts and i cant do that as OTP is coming to that number.
