Debt collector or…?

Got a call from Carrollton Texas: 972-300-000.

Said he was from "Card Services" Called me July 4th. Who calls people on a statutory holiday?

July 4th must be the day they call PA residents as someone else reported receiving an unsolicited call from them today too. He told me I had a $5000 debt. I don't owe a cent. Started to say this was a new phone number and they probably wanted the people who had it last. The caller hung up in the middle of my sentence.

I suspect it's an identity thief... someone trying to con people into giving up their name and credit card numbers. Angry behavior like hanging up usually indicates lying.
