Erroneous Billing and interferring with my credit record

Once again, I am very disturbed by what VODACOM has done to me. This is the second time it does this. In 2015, they let someone open a phone contract under my name without my authorisation or relevant checks, signatures or proof documents. How I found out about this is on 23/03/2015 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. Fast forward to two years (on 30 Nov 2017), I went to apply for a home loan but, I was declined and told that I must first settle my vodacom account and get a paid-up letter. I went to VODACOM and demanded an answer as I do not have any account with them. They acknowledged this error and I was told that a Supervisor would call me and I was going to be sent a letter. I have still not received any calls. I called them and I was told that I would be sent a letter in 24 to 48 hours. I called today to follow up and now I am told that I will receive the padi-up letter next week Tuesday. This is really wrong. First they mess with my credit record and now I must wait for a letter for days instead of them just sending it to me so that my record can be cleared.

This was sorted out in 2015. Why does VODACOM do this again 2 years later? Is it right that they just mess with people's lives like this? I think I want to report them to the National Consumer Commission because this is not right. I have never owed them but, they just submit false information to credit scorers about people.
