The calls are sequential, not random.  Robo-dialing starts with numbers ending in -0001, the 0002, .... , through 9999. It's cheap, it's fast, and if one sucker gives them personal info, it's a bonanza.

Good luck stopping it, though.

Just another one of the spoofed number used by the "card services" scammers. Google my name to learn how to eliminate their annoying calls, while also having some fun!

Poor old Gugliemo (if he even exists) has to take the blame for these calls, when it is actually the "card services" scammers calling, using a spoofed (false) number. They pretend to be associated with various credit card companies, when actually all they want is to get your credit card number so they can rip you off!  They prey on the elderly and the gullible. Others must be made aware so they are not taken advantage of. The unsuspecting have lost hundreds, if not thousands of dollars to this scam,run by drug addicted telemarketers,trying to support their disgusting habit!  BEWARE!!!!!

I've reported this number to the do not call list, but it seems nothing is being done.

ID=New York Call.  Recording beginning with something like Card Member Services.  I hung up.
