First National Collection Bureau Ripoff Sparks Nevada

I would like to inform that I have received a call on Thursday April 30, 2008 from First National Collection Bureau Agency to inform me that I have an account (Associate Master Card) with them with a balance of $4,500.00 Account was opened on November 4th, 1999. The account went to collection on 2000.

I informed them that the account is not mine because I never had an account open on 1999 and I never lived on any addresses that they claimed I lived. They told me that I was a lair and they will take me to court to withold the money from my employer or bank account. I asked them to send me any documents that support what they are saying cause I can prove and show that the account was not open by me. becasue I was not living on Connecticut when the account was opend. I am not sure what to do next?
