Navient Debt Collection Complaint

Navient Debt collection department,

I do not know Disclosure verification of debt Right to dispute notice not received Kansas

General Revenue Corporation sent a letter dated on -/-/- about an alleged debt I do not owe. In the - paragraph they state that it is their second attempt to notify me of the debt yet they have never contacted me before nor have I ever heard of General Revenue Corporation until today -/-/- when I received their letter. Nowhere on the letter does it say I can dispute the debt. Also there are - different addresses listed on the bill in - different towns out of - different states. The average consumer would have absolutely no idea what address to send a dispute to. The letter claims that I owe for a loan where I have never taken a loan for whom they are claiming to collect for in their letter. Absolutely none of my rights are stated in their letter to me and the language used is to demand payment giving me no option to dispute anything regarding their false claims with them.
