CANT MAKE PAYMENT ARRANGEMENTS WITH TELKOM?!

I have a ADSL line and due to some financial difficulties fell behind on payment. I have contacted the center on numerous occasions to ask if a payment arrangement can be made and the line cancelled, but they refuse until i can pay 40% of the outstanding amount which i cannot. my line was suspended from the second month when could not make payment. i am on month to month term and cannot see why payment arrangements cannot be made. So every month, Telkom is adding another R699 for services i cannot and do not use. I have asked them to please then hand me over so i can make payment arrangements with those people, but this they refuse also until the 8th month. So in other words, when they do eventually hand me over, my bill will be standing at about R7000 for services that was suspended when the bill was R1200, and of which i offered to make payment arrangements for?! This is the first company of which i know of who purposefully increases your debt before handing you over.
