Unauthorised charges on cellphone bill

I recently discovered that a daily charge of R7 per day had been added to cell phone charges. This has escalated to such a level that I am unable to load any top up airtime.<br> When contacting my service provider I was directed to Mirror Networks who in turn placed the blame on Cell Spice. Their explanation was that I had subscribed to a additional service during 2013, but when requesting documentary proof of this, they asked me to send the request in writing. I have comp**** with their request, but have received no response. This is of great inconvenience to me as without resolving this the charges will continue to be added to my account escalating to an unaffordable level.<br> If I am unable to get a response and subsequent refund I will have no alternative to take it up with the Consumer Protector as well as the National Credit Regulator.
