Same as the other posts. They've called twice today, twice yesterday, and 3 or 4 times yesterday as the 617 number. I haven't answered and they never leave a message.
When I saw the 555 prefix, I knew it was fraud, so I just sent the call to the FAX machine! LOL! I love doin' that! Give 'em a big squeal in the ear and that'll make 'em mad as Hell, at least! "Go ahead and call me back!", I think... :-D
Two things. No one sits there dialing phone numbers. That went out decades ago. So the only thing that will hear that squeal is their computer and it don't really care one way or the other. Further, there are some legitimate 555 numbers. Look it up.
