Attempts to collect debt not owed: Debt collection

I was a victim of Identity theft in 2018 there were multiple accounts opened up in my name fraudulently. IC SYSTEM is reporting a collection account that is fraudulent and I want to submit a formal complaint against them. have identified the accounts and now am able and have the spirit to fight this challenge and work on getting my life back. I work full time and raise a family and this has caused a great deal of stress on my family. Filed the FTC Fraud report and contacted the companies reporting the information as well as contacted the police. Please help me fight this and get my issues resolved. Thank you
