Caller ID showed "Monmouth Theater".

the call is from Maine

Monmouth Threatre with a pre-recorded message concerning eligibilty to restructure existing credit card debt.

Doesn't seem to check the Do Not Call Registry and doesn't mind disguising themselves with a fake identity.

The actual number belongs to a theater boxoffice in Monmouth, ME. I called the number and the theater is aware that scammers are using the theater's number to "mask" their own. The last time I got a call from these scammers, I checked with the bank that issued my credit card. The number that time was a number in Manhattan (NYC) but was not in the bank's own directory for NYC. Local rep for bank advised that only cc issuer can change card rates and even if they do they won't contact you via phone.

"Important call" regarding my credit card.  Odd since I don't have a card and I'm on the do not call list.  I pressed 1 to speak with someone, asked her how she got my number, she said "You called me" and hung up on me.  Monmouth Theater showed on caller Id.
