********** accounts in my name

I realized that someone opened two accounts with my details and bank details with Vodacom. These accounts were added to my profile and debit orders were adjusted to include these accounts. I phoned Vodacom on the 6th of January to notify them that these accounts are not mine. I was instructed to get bank statements (bank stamped) with my ID certified by the police station as well as to make and affidavit stating that I did not open these accounts and fax this information with the numbers of the accounts as reference to *** 9 Jan 2015. (It required me taking off work to get all of this information together!!) The contracts would be cancelled and in one month i will receive my money back. So this month the same debit order went off my account and no money returned. I phoned Vodacom again (also noting that I am not a Vodacom cellular client so these phone calls are for my account). After speaking to 8 different people who directed me between accounts, legal, *****, customer service, I spoke to someone that said they will sort it out and phone me back before 3 yesterday. I still have not received the phone call and I do not know who to talk to sort this out. Please help!
