My question involves collection proceedings in the State of: GA

My issue is different than most that I have read. I have been receiving a call from a 877 number on my cell and at my place of work. They claim that I received a payday loan and that i committed fraud. They also claim that they will take legal action against me. They have called so many times it is officially harassment.

Fact: I have NEVER received a payday loan or any type of loan aside from my student loans. This individual that continues to calls reads me all of my info over the phone from my date of birth, address, employment info, etc. I never confirmed any of it but how do I handle this situation? Can I sue this company for harassment?
