I don't have a contract with Vodacom

Somebody took up a vodacom contract phone with my id number, I've queried this with vodacom and they asked me to get an affidavit and email it through with a copy of my ID. I've done this twice and even went to a vodacom shop in Sandton. I had requested to see documents submitted by the applicant and they gave me a ********** bank statement that is obviously ********** because it even has a transaction for the 30th of February. How this contract was opened is beyond me. Today I get a call from an attorney saying my account was handed over . why ask me to submit documents then if nothing was going to be done? It is your incompetence and I want my name cleared, who the hell looks at a bank statement with a transaction for the 30th of February and approve it?
