3rd party service provider

I have signed up on a contract withRMCS for a age mobile cellphone of which I pay R389 pm every month.the end of september I had my phone ****** and then requesteda sim swop as I am paying for the contract.after many emailsdue to not being able to contact the relavent parties I was told to pay R150 for my sim card and it will be delivered. After paying it and sending proof of payment I had to wait almost 2 weeks for it and now that I have the sim card it is suspended. I tried calling cell c and they gave me a call centre number that I cannot get through to because the number is suspended. Its been 2 months and I still don't have any service and cannot get hold of anyone that can help because RMCS says ag mobile must deal with it and cell c who is the network I'm with can't help because of the 3rd party stuff.I am angry and sick of being taken for a ride after losing my phone and having to pay to use my contract which I pay for and I am still unable to use it. If no contact is made within 24 hours I will be forced to take the legal route.
