It's a debt collection scam. I received an email from someone stating I had a delinquent account in the tube of 2999.96 and I needed to pay it or I would be sued. I was also called by this number and a man by the name of eric Dermont stated I  would be sued if I didn't pay at least 600 dollars and send it to them via a green dot money pac card. If you get contacted by them report them to the ftc.
