RMCS a **** that deserves to be sued!

I am one of many who clearly needs some clarity on this company RMCS because apparently they work with EDCON. I only found out about them and that they have been billing me from my Edgars account. I never agreed to such and when you call, it is either they dont answer or claim that they have forwarded your query for a refund. over 2yrs that they have been charging me but not once did i receive either their data or airtime. This company needs to be sued.
