********** account open under my name

I am disappointed with cell c service , I currently have a data contract with Cell c which started last year May, unfortunately on the 3rd August I received an SMS saying I am opening an account and if I am not the one I should call 084 151 by the time I saw the SMS it was 30 minutes late but then I quickly went to nearest branch in Mall of Africa to investigate what is happening, I was informed by one of the consultants that a cell phone contract was open under my name at the CNA store in Durban Pavilion mall and this was easy since cell c have my documents because I have a contract with them, the consultant then called the CNA store and he was told that the person who deals with contracts already left the store and he will be available on Monday, I was requested to go and do affidavit to confirm that I did not open the account and it is a *****, I did as informed and gave the affidavit to the cell c consultant and they send the affidavit and my ID copy to logistics department, and I was told to call CNA Pavillion mall and request the manager to open ***** case because it is not cellc’s jurisdiction but CNA. I did as told and was asked by CNA to submit my documents to them so they can send to ***** department and this will be reverted and solved ASAP which I did send. I never received any call from cell c or CNA store informing me if this was solved or not besides receiving a debit order of a phone which I did not purchase, What I am failing to understand is if cell c have my documents meaning they have my id copy, bank statement and proof of residence how did a person, with only a **** id which only had my first name and wrong image manage to open a contract and worse of it all she only submitted just a **** id copy ,no bank statement and proof of residence. I will really like this to be solved ASAP because it is causing me unnecessary stress.
