Telkom Mobile nightmare

I am the victim of Identity theft, someone opened two Telkom mobile accounts in my name. After stopping the debit orders in 2020 as soon as I realised this, I have been trying to cancel the accounts, report the ***** to Telkom and trying to clear all cost to my name- but after numerous failed attempts (phone calls, emails, in-store visits, Facebook messenger) Telkom has now blacklisted me for non-payment, and the accounts are still open and the ********** is still using the mobile accounts. I am so frustrated and have no idea what to do :(
