********** contract opened under my name

I am very disturbed by what VODACOM has done to me. Letting someone open a phone contract under my name without my authorisation or relevant checks and signatures or proof documents is unacceptable. How I found out about this is on 23/03/2014 I woke up to a sms from my bank saying that VODACOM debited my account. When I called VODACOM they said I opened an account on 19/03/2015. I said this was false and demanded them to give me proof. They said I needed to go to the Police. I went and got an affidavit then faxed it to them as per their instructions. <br> <br> They gave me incorrect contact details of their forensic department and **** that someone would call me after 48hrs. It has been more than 4 days and no call or sms. VODACOM has messed with my credit record and now I am not getting help from them. I keep calling their call centre and their call centre agents keep playing games with me sending me from pillar to post. I am not sure who to approach now but I need to get legal assistance or lodge a formal complaint against them as I dont understand how they authorise a cellphone contract without calling to check with me or without my signature or id copies etc.
