Telkom debiting my bank account for two ********** accounts

A person I do not know opened two accounts with Telkom **********ly using my name. I informed Telkom about this and submitted the documents they requested from me and they opened a case of ***** but they are still debiting my account (R2 030.07) instead of suspending the debits while they are conducting their investigation, which they say it takes a long time. This is a huge financial inconvenience for me because I cannot pay for the things I budgeted for while Telkom has taken my money without my approval. The two agents I have spoken to at Telkom were very helpful but there is so much they can do, they can't stop the debits themselves. I cannot understand why they should continue to inconvenience me instead of stopping these debits.
