Collection of premiums after I cancelled

I went to Autopage probably 18 months ago to cancell. I was on month to month and under no contractual responsibility with them. When I tried at the Tyger Valley branch the sales person tried to sell me new contract and after I strongly suggested that I don't want the cell number anymore, he stated that cancellations cannot be done at branch level and gave me a number in Johannesburg the phone. This number was an incorrect number!!!!<br> <br> I then instructed my bank to stop payment immediately. As I have no contract with them it should be sufficient indication that that I do not want this anymore. I recieved no further correspondence from them. After more than 6 month I received my first phone call from attorney and requested that they send me the information. Nothing! <br> <br> Now after another 6 months I recieved another phone call from a different attorney who slapped on another R600 to the bill. I again asked for the details but they just don't send it to me.<br> <br> This is terrible service from Autopage and completely unacceptible.
