Please help

Someone opened an RCS account on my name, was told to get an affidavit from the police station and sent with a copy of my id with 3 of my signature. Which I did I sent the doc on the 19 of May 2020 and today is the 24 and still nothing. I understand with the covid 19 things are a bit hectic but at the of the day its not my fault cause I don't understand how can someone open an account using other peoples identity and I never sign for anything but now am in debt ... and now I want to purchase something and I cant cause of this is lowing my credit score.
