Billing for non-service

I responded to Multichoice promotion on the DSTV Explora 24 months contract for R799 per month. The decoder was delivered during February but since I was only going to move to the new house at the end of February, I did not install the Explora until then. To my surprise, Multichoice deducted R1331 extra on my account at the end of February<br> <br> Firstly, the contract is for R799 so what are other fees for? Secondly, how do I get charged for a service I did not receive during February? I called the Multichoice customer service and was advised to send the DPP sms again. The agent who called back kept arguing about the terms of the contract before agreeing to escalate my query. I am not even sure if she did that as I never received any feedback call. <br> <br> I still do not have clarity or my money back and am highly disappointed in Multichoice. This feels like a **** as one cannot call them directly but only send an sms and hope they call. How can such a big company run a promotion with no inbound call centre?
