Yes the exact same as above.  They have called 5 times today.

Got a robo-call saying they wanted to verify charges on my credit union Visa. When I call back, they want all 16 digits of my card. Problem: I don't have a credit union Visa with the last four digits they asked for. When I googled them, it said Envoy Financial Services of Florida.

same thing happened to me. gave me the last 4 digits of an old cc card i had.
