No notification of increase

I recently received an invoice from Autopage showing that my monthly charge has shot up from R189 to R299. I called this morning to query this, but nobody answered the phone. So I sent an emailed query. They sent back a reference number 683821. A few hours later, they closed the service request, without bothering to explain the increase. When I called again to query the whole situation, the call centre agent kept telling me that Autopage had previously notified me of the increase and had also responded to my query today. I disputed both of these. He insisted that I was lying to him, and rudely refused to listen to my side of the story. Then he hung up on me.<br> <br> Autopage - please contact me urgently via email, ie. in writing, so that I can formally cancel all contracts I have with you. I refuse to deal with companies who have absolutely no respect for their clients.<br> <br> Thank you.
