Impossible to cancel a contract that was incorrect.

<p>I received this amazing deal over the phone, R120 for 10gigs of data including a Wifi router, which turned out to be only 150mb for between R700 to R900 per month.</p> <p> </p> <p>I received a call for Telkom with this special offer in July, after recieving the pakage I soon realised that this is not what I agreed too. I went to into a Telkom outlet to assist me with this matter and they could not find me on the system. It turns out that this was sold to me using a third party company and they are the only ones who can cancel this deal. After spending 4 hours on the phone I found the company I was dealing with called Velociti and they where more than happy to assist. They agreed that they had made a mistake on their side after looking at the voice recording, which I have on Email. They said they will cancel this as soon as possible. It has been four months now and everytime I call them back they said they are still busy with the process, since then Telkom has been taking between R700 and R900 out of my account each month for a device I'm not even using!!</p> <p> </p> <p>I cant belive that they can sell a product using a third party company and then turn around saying that this is not their responsibility and still take my money each month.</p> <p> </p> <p>Please can someone give me any advice on what to do, as I am now sick and tired of this ****************!!!</p>
