Autopage - ******* SERVICE AND **********

I have noticed the Autopage has cancelled my 5 gig data bundle from my account and now billing all my data at the out of bundle rates. This is for my last bill (invoiced already) and my current bill (not invoiced). This is unacceptable and is tantamount to *****. I have all calls recorded with all my conversations with Autopage is i always make sure i call them on our recorded lines at our office. I request all proof of cancellation be sent to me IMMEDIATELY. I am not prepared to pay R3000 + for out of bundle data usage and i have had a 5gig data bundle attached to my billing for months now. This is ripping us as customers off, and maybe i should approach CELL C to buy out my contract with you guys. I am definitely not going to pay this excessive amount and i am prepared to take this to court. Now my phone line is damn suspended. They responded to my post on the 27th of May, and up to now no one has had the decency to call me, but they can easily suspend my line.
