Called twice and hung up both times after two rings.  When I call back from another unlisted number I have, you eventually get an automated voicemail saying "The person at extension 5 is on the phone", and then a voicemail beep.  This idiot is blocked.

I just got a call from this number. Caller ID was "Billerica MA". I didn't answer and they did not leave a message.

Call from this number! I answered the jerk hung up ! I called right back just kept ringing!

"unknown caller" in the id field, but accidently picked it up, pedling composit windows to a registered "do not call number", so obviously does not care about laws, just perfect to buy home improvements from....
