Some guy trying to sell credit cards with better interest rates. Claimed he knew about what credit cards I held, but when I asked him for details he said the "Visa and the Master Cards", neither of which I even possess. When I informed him of that fact he became very agitated. I could clearly hear others in the background, so this is definitely a boiler room operation.

If your fishin in my pond your gonna need better bait.

Did not recognize the number, so I let it go to voicemail.  The message they left me said,  " this is federal".  The caller was female, and she yelled this is federal,  almost a scream. B
