wrong debit on bank account

Vodacom had for 3 times deducted debit orders on my bank account for accounts that does not belong to me. the amounts was R3, 000.00, R10, 000.00 and R17, 000.00 for the months September, October and November causing my account to be in an negative and my own debit orders not to go through. this is in fact *****ing money from my account as I had not given any authority or permission for such debits. My debit order for Vodacom is R321.00 per month, see the copies of the wrong and the right debits done. 2017-10-02 DEBIT TRANSFER VODACOM ********** 602 KN003 ********** R 10,229.98- 2017-11-01 DEBIT TRANSFER VODACOM ********** 716 KN003 ********** R 17,430.32- 2017-08-31 DEBIT TRANSFER VODACOM ********** 490 I ********** 9917 R 321.39- Should this continue for December I will have my attorneys handeling the case and this will include ******** charges and civil actions against Vodacom.
