TABLET CONTRACT NOT THROUGH TELKOM

I receive a marketing call from a Telkom call center agent offering me a tablet for R90.00 per month, I agreed give my details and am billed immediately for the R90.00. Only after billing has been done do I realise it is not Telkom contract but a company called Cell Direct?<br> The story goes as this, When I checked the Internet to find out who they are I discovered they are a company in Cape Town, checking Hello Peter as I always do prior to any purchase I discovered all the billing complaints and other are many. I followed up with them to see when I would receive my hand set and they cannot confirm a delivery date, I immediately cancelled the order and the contract. I spoke to an agent who advised I would receive my R90.00. Today they say no, I lose the R90.00 because I cancelled. I did not cancel out of choice but because of the bad reviews, I refuse to bind myself to a contract for two years with a company who do not know what they are doing. I want Telkom to advise me why I was not informed by their sales that the contract would not be with Telkom?
