I recently received a letter from a law firm informing me that i have a judgement against my credit for $4500.00 and they want to collect. i did a lil enquires and found out that it was posted in Queens County civil court sometime in 2009 unknown to me. i did recall having a citibank account sometime in 2000 but it was closed since 2002 because of economic reasons. it was also discovered that the original debt was $1699.42. this was done in my absence, i was never summoned to court to address this...Is there anything i can do to fix this?
