Popi act........ Vodacom doesn't check.

A *****ulent account was opened in my name. This person managed to run up a bill of R6000 . I contacted Vodacom ***** division in September. Gave all the documents they asked for. To date the issue has not been resolved. I get phone calls from Vodacom asking for the money. How do Vodacom perform Rica,FICA checks. I don't think they do. Can someone with brains please contact me to resolve this.
