Extended contract with out permission

For the last 3 or 4 years I have been using a 8ta 10 gig ****le for R200 a month which I was extremely happy with, but over time my internet usage was exceeding the 10 gigs and so I decided to install a uncapped line.<br> <br> So roughly 5 months ago I went into the Telkom shop at bayside to cancel my line, which I assumed was fine as I knew I was on a month to month as I had finished my contract a good year before and was just on a month to month basis, however the consultant informed me that my contract was renewed a few months before, I informed her that I had never agreed to renew my contract and I want the recorded conversation that proves I agreed to such.<br> <br> This started over 5 months ago, since then I have been into the stores more than 5 times, and each time they say they are working on it, I am still getting debited every month for a product I do not use nor did agree to use.<br> <br> This is extremely frustrating that I have no control over this and cannot stop this debit order or I will be blacklisted for something I have never agreed too.<br> <br> I have a case number, if there is anyone out there who can assist me with this, I would be greatly appreciated.
