Some sort of low life collector dealing in worthless paper and abusive unlawful tactics. Just Ignore them. Never give them a penny. NEVER give them a checking account number - they will clean it out. They will not sue - they are dealing in junk paper that gets traded for pennies on the dollar. You can try sending them a Bud Hibbs cease and desist letter.

May also be connected to (901) 569-5690 and (718) 439-6602. New York seems to be the home of a lot of shady "collection" operations, and we all know what a toilet Brooklyn is. Meanwhile, Atty Genl Cuomo spends his time going after Intel.
