Contract Cancellation

I am so ****ed at RMCS this is a joke, I lost my phone last year September and when i tried to blacklist my phone on Vodacom they told me i am on contract with another third service provider, which i never app**** for. I then called RMCS to blacklist the phone, which still today dont have an ITC number to claim my phone. I have been calling RMCS every week and surely this is one of the most bad experiences i have ever had. I have requested cancellation back to prepaid and after every 24 hrs there is a story. What kind of an organisation is this. You cant even call the cancellation department straight they tose you around. RMCS is bad customers take hid, Edgars stop this on our accounts of giving us contacts we do not even know its very bad for your company.
