Telkom relocation order can not be cancelled

Have been struggling to cancel my TELKOM line In June I did a online line relocation order as we were moving at the end of June. In August Telkom installed my new land line at my new address. My old line was never cancelled and I am still getting billed. The ADSL portion of my line is with Afrihost, and they are also still billing me for it, as Openserve is still billing them. There is a open relocation order on my line and nobody at Telkom is able to help me to cancel it. I have been to the walk in Call centre at least twice a week now, and also phone 10210 every second day. I get transferred from accounts, to new services, to technical but nobody can cancel it. I am paying the new line rental, but both numers are on one account and now Telkom wants to cut my current line. I have just about had it with this company.
