Account opened **********ly with my ID

On the 22/10/2015 I became aware that I had been blacklisted by Telkom Mobile which alleges that I have defaulted on payments in respect of a Telkom Mobile account opened in my name. Although I do have an ADSL account with Telkom I have never opened a Telkom Mobile account. Even though Telkom has my contact details due to my ADSL account, I was never contacted regarding any outstanding payments?? <br> <br> Once I was aware of the blacklisting, I made contact with your call center and Fourways Branch in order to report the **********ly opened account and was advised that Telkom would investigate within 21 days. I provided the requisite affidavit, a copy of my ID and a proof of residence, the 21 day period has now lapsed and I have not heard anything at all. <br> <br> Through my own investigation, it has transpired that the account was open in Somerset Mall in the Western Cape although I live in Johannesburg. I need to know i) which ID copy was used to open the account, ii) proof that the sim card was RICA'd, iii) an explanation of why I was not contacted regarding the amounts outstanding prior to being blacklisted. This must be resolved ASAP as my credit rating is being adversely affected.
