I've learned from watching a story on one of the national news magazine shows that these losers use computer programs that change the info displayed on Caller ID, so the info you see on your phone may be completely fake. For this number, the Caller ID says it's a cell phone, but when you call the number, you get a message that it's not a working #.

I keep getting calls In PA about carpet cleaning. I press option 1 to say I will take it just to talk to someone. When I do and say I have repeatedly asked to be placed on the do not call list and they have just violated state an national laws they simply hang up. This process continues once a day.

May 01 5:15PM  I'm in Pennsylvania. A recording about carpet cleaning.
I do not press any buttons to respond to these criminals.
That just confirms they have a valid phone number and they keep calling.

Same ROBO-CALL "hi do your carpets need cleaning" that everyone is reporting.
Have logged it on the DONOTCALL.gov site, but seeing as how these robo-calls have been coming for over 2 years to my cellphone (that I don't generally give out).... I don't know what else to do to stop them.

No answer when I pick up, only dead air.
