They are a debt collection agency- Allied Interstate. They usually go after people for student loans. They are kind-of shady from what I have read, but I don't know this from personal experience...they called me at work, I told them to call back after, so no real "dealings" with them yet.

They are total trash!  Do NOT deal with them at all unless they validate their claims BY MAIL & you have checked that the debt is valid.
Statutes of Limitations regarding debts vary by state. Check yours. If Allied is calling you, you can be sure what you'll find.
Be Safe. Be Aware.
