This number called and said they are from Clearview windows, but when you try to call the number back it says it is a "Google Subscriber." Why would a company not allow you to call them back? I don't believe it was really Clearview calling. They started asking me questions like how many windows I have, if I have a sliding glass door (great for a robber to get into). I may be being paranoid, but better safe then sorry. I ended up just saying we are done with this call and hung up.

Google Voice.

Google voice is great but you have to start with a clean number.  If people already have your real phone number there's nothing you can so.

Call was unanswered-I did not recognize number-there was no message left!  Not interested in doing business with an unethical telemarketer!

Got the call a little while ago. Like others have mentioned, if you call back, it's a Google number. Just got a call back to confirm the phony appointment I set up and the phone number was 714-729-0680  and Caller ID displayed Clearview Const. I was tempted to have the scumbags actually show up for the appointment and try to get a business card, but just didn't feel like dealing with it today
