Debt collection — Amsher Collection Services, Inc. (TX)

Debt resulted from identity theft. I am a victim of identity theft and noticed a collection from AMSHER COLLECTION. I 've attempted to dispute multiple times however no response on their end. Not sure what else to do. Police department told me to contact the federal trade commision which I wrote a formal complaint against AMSHER COLLECTION in regards to this matter. The FTC also instructed me to complete a id theft affidavit through identity theft.gov. Attached is my document. Thank you
