illegitimate opening of an account in my name

on 27/10/17 a "top dog" account was opened in my name at Vodashop in Incredible connection (I.C.)Sandton. R 11000+ has been spent on this account. I begged I.C and Vodacom to block this number and they refused. I deal thru Atterbury Vodacom. Stephanie helped me. Very helpful. I made an affidavit at Garsfontein SAPS. also very helpful. This no ********** 824, was opened under name CHUENE. she works at Voda*** in I.C. at Sandton. Neither her nor her sup were helpful. She denies any knowlegde but admits her password and details were used to open this account. How can that be? Vodacoms security is up to ****. I was never informed of this account by sms and it doesn't appear on my account. just taken off my Debit account and Voda*** wont switch off that number or trace it to put the ******* behind bars.
