scammers calling my DNC listed #. Sometimes I wish I could put an air horn in the transmitter and push the button. :)
Criminals and scammers are the only ones that call DNC listed #'s and refuse to leave a message with a call back #. Real businesses would leave a call back # to get the business. Criminals and scammers will be found by law enforcement if they leave a call back #.
Called service department direct line. Caller ID looked fishy ("INFO GUIDE") and number was unknown. We let it go to voice mail but caller hung up while voice mail was still making its announcement.
They are not. Remember that professional scammers (a.k.a. criminals) are very creative to show a caller ID that seems legit. They pretend to be, banks, charities, and even the IRS. If the call is important, they would leave a message; and even when the caller leaves a message, it could be somebody looking for personal info for devious purposes.
