Identify theft/********** account

In March 2020 i made a review about identity theft/credit ***** that was done under my name,in April a lady from Homechoice customer relations contacted me requesting supporting documents, ID copy and an Affidavit. That was done and i was told it is sent to their ***** department and it takes 1 to 3 months to resolve the issue through investigation. 4 months down the line while noticing my monthly credit report reflecting negative due to Homechoice i contacted her again to be told told investigators are still busy. 6 months down the line investigators are still busy as being told, Now approaching my 8th month with no feedback and my credit score and report is in shumbles. This is driving me insane.
