Homechoice bad service

Someone opened a *****elent account on my name.This now reflects on my ITC and I have never bought anything from Homechoice.Sent through an affidavit and all the details.Its 2 months now and havent heard anything from them.When ypu phone you are told everytime that the investigation is ongoing.How long do they want to investigate???And now all this extra debt reflects on my profile which ia not even mine
