Billing me don't even have lines with them.

We ported our number away from telkom because they could not supply us with lines because they kept getting ******. This happened in April 2017. on porting request we requested that all lines be cancelled with telkom. Then in October 2017 Hendrik Swart from telkom requested the porting documents again to cancel our infrastructure that has been sent to him. Now they want to hand us over because they do not do their job. We don't even have lines with them and they just keep charging with no help from their accounts department. I am paying my current supplier for the lines and it has been ported long time ago. Have proof of all correspondence with telkom. also have documentation of cancellation and proof that it has been sent.
