Illegitimate debit orders by Telkom

I'm awfully disappointed with Telkom. I am being debited for a contract I did not take out. From the 30th of October 2021, I saw an increase in my Telkom debit order. I paid an estimate of R1688 in that month and in December the debit order amounted to R2879,47. When I enquired with Telkom I was notified that there was a contract at Telkom Jabulani mall that was taken out using my identity. I have been given two reference/case numbers for this matter, ***7 and ***7 but on multiple instances I received a notification that the matter is closed. Upon enquiry I am told that this matter has been referred to another department. I am tired of moving backwards and forwards with this query. Telkom have sold this contract without proper due diligence and are now holding me accountable for it. I am tired with this poor service and need this matter resolved urgently. Telkom service regarding this matter has been The worst I've have ever experienced.
