********** account opened in my name

I had an account **********ly opened in my name with Vodacom in December 2016. In March 2016 I went to Vodacom Eastrand Mall to report this account after debit orders were added on my account. I spoke with this young lady who took my affidavit, ID copy and proof of address and told me it will be investigated and resolved. This was never done. When I requested my credit report in July 2016 this account was still there, and it affecting my credit rating. I called Vodacom requested a copy of my Contract, they couldn't provide it, lodged a dispute with their forensic department, but still to this date nothing has been resolved. I am now thinking of getting legal advice on the matter.
