I had to answer because I was expecting a call from this area code. The usual dead air for 4-5 seconds - then sudden onset of background noise (like a boiler room) and someone asked for me by my first name. When he said he was a licensed contractor I hung up.
This creepy guy called our landline 3 times within 5 minutes, said he was a general contractor and knew my first and last name. After I told him that we have a no-call phone number and to not call here again he started arguing with me!! I yelled at him and told him to never call back. He immediately called back! I answered totally annoyed like "seriously?!?" and he was still trying to argue with me! I told him again not to ever call back and hung up. He called right back AGAIN!! I didn't answer though and he stopped calling. That's total harassment, not cool
Caller ID simply states "Cell Phone CA" and person leaves no message, but calls repeatedly despite my being on the do not call list. I will report to FTC.
