Billed for unwanted value added services

I also got billed for services witch I have not agreed to. I agreed to receive my phone from Elite Mobile, only after the caller told me he was from Vodacom! I told him I was planning to go the Vodacom shop to upgrade, but that fact was completely ignored. Nobody asked me if I wanted all the \products"";but have been billed for it! I want the bills cancelled and refunds for EM-*** 1 to 6."""
