(508) 475-1374 has called my office multiple times in a day for several weeks. I answer the phone and they hang up. If I let it go to voicemail they do not leave a message.
I get several hang up calls each day at work from this number. Today I finally got more than a hang up "you've received two free curise tickets." There is no way to opt out.
This number has called my office multiple times as well hanging up when the phone is answered. It's very annoying...Watch out for 508.475.1378 because this number does the same thing also.
