Edcon-RMC Partnership

My story is quite long but for the purpose of this review I'll make it as short as possible. I was signed up for a mobile content product without my knowledge with a company called RMC that is in partnership Edcon last year July. I had no knowledge of this product until June this year, this was brought to light due to the fact that I had settled my Edgars account at the beginning of March with a mobile company called RMC. When I realized that I was wrongfully charged for this product, I logged in a call with RMC for product cancellation and refund of the amount charged on the account. RMC advised that the product will be cancelled and a refund will be effected within 5 working days, this was back in June. The product was cancelled and no refund has been done to date, after sending emails and calling the agent picked up the call. To my surprise, I was advised that the refund was declined due to me having taken the product through telemarketing. This is a complete lie!!! Who in their right state of mind takes a product they have absolute no knowledge of!!! Even so, when they declined the request, no one bothered to notify yet I've called several times. Seeing that they claim I signed up for the product, I requested for them to produce proof of which they have failed to do. I refuse to pay for something I did not sign up for. Edcon, kindly assist with resolving this matter.
