939-930-1617 carmen from card holder services , using a Puerto Rico area code, A scam id thieves now using an expensive callback number for those that hit redial on unknown callers,
always check the area code if you're one of the hit redial people, a call blocker only works if they call from same number, they spoof a new number almost every day when calling me, I went without answering unknown numbers for over 2 years and it didn't cut down on bogus calls at all.
