Who called from 7879571305

Call Came at midnight. A recording indicated my credit card had "fraudulent activity" but did not indicate what card.

Your Columbia credit card had "fraudulent activity" and now is blocked
please talk to rep to fix the problem

I don't have Columbia credit card

Area Code 787
Area Code 787 is designated as Puerto Rico (overlays with 939), was split from 809.

Call came at 11:30 last night, with a text-to-speech voice saying something about a Polish National Credit Union Mastercard (which we don't have). Definitely a scam--we and hundreds of other people called the local PCNU today to find out what was going on. Apparently some people around here got calls at 2 in the morning...

Automated call said my Coors Credit Union Card had a fraudulent charge made and therefore the card had been blocked.  I was to press a number to unblock it.  I don't have a Coors Credit Union card.
