Hello Peter i have a problem with this company called RMCS

On the 08/11/17 i tried to make a sim swap on vodacom network and i couldnt get help just because they told me i have a contract with RMCS and the contract is for R50 airtime,i never took or sign any contract with this company. I went to vodacom to query this and they told me they have nothing to with this and ibaskd them its been more than 10 years have this number and i never joined any contract and i tried to send emails to them and i got a response from a gentlemen called Themba and he sent an sms saying they logged my complain and a week after that on tuesday they suspended my number i can not make or recieved calls and today its the third day,worse am away from my kids that i used to call them everyday. Please help me Hello Peter these people are taking an advantage of me and i have a strong feeling that vodacom have a lot to do with this. No compay have a right to dig in other company's client base to take thier customers. Please help
