Debit order paid against a stranger's telephone account.

I have been trying since March to get a debit order which went off my bank account, and which was paid into someone else's telephone account (by Telkom), re-directed to reflect against my own account. I have spoken to Customer Services 5 times already and have also submitted numerous documents as proof. Telkom can even tell me against who's telephone account my debit order had been paid. All I need is an internal correction from their side. Unfortunately no-go. I will keep on trying though. Just find it strange that there is no ombudsman to plead my case with.
