AUTOPAGE- DONT KNOW PROFESSIONALISM

I did post my complain here with autopage concerning the cancellation and conversion to prepaids. After much of a battle and the company consultants and staff being unable to read the word cancellation and conversion to prepaid...deactivated the number. However, its EIGHT DAYS since the number has been finally working but not yet converted to prepaid. In terms of my contractual arrangements this number was supposed to be converted to prepaid on the 28 June. I keep calling them..either the call drops and they dont return the call...yet their recorded message says please punch in yr number so we know how to attend to yr call....and when i do get hold of a consultant i have been promised on Monday the 3 Aug with reference number 792060 that it would be converted before the end on the day. Its the next day and no luck. I am being billed contract rates. Which means the company is *****ing money from my account. Please advise is there any procedure i could follow to log a complaint with CPA and how do i take action against this irresponsible behaviour as well as the non compliance of contractual arrangements.
