unrealist billing and bad servoce

i have been a client with Auotpage for a couple of years, always paid my account via debit order until the debit order amounts got out of control about two years ago, I have stopped my debit order and paid the account manually every month so that I have better control over my money. I have continuously tried to get a itemized bill every month to try to establish what have coursed the very high charges on the bill, no one could explain, I also went into Autopage Secunda where the assistant phoned Head-Office on numerous occasions to try to solve the problem but without any success., I have cancelled the contracts I have with the Institute after the expiry date of the contract and still made regular enquiries every month in attempt to understand the charges and to finalize the account, the latest correspondence made dated the 6th month of this year. Where after the Company handed my account over to a Legal Department for a fee/account of over R15 000.00. on all my request with them to send me a itemized bill on how they came to this enormous amount, no one could submit the bill, I am not going to pay this account and want the customers to be aware about this unacceptable behaviour<br>
