In my opinion DO NOT ANSWER I had the same experience as many people have had on here l answered and after a delay a woman's recorded voice said Hello and Goodbye I think this is a test call to see if there is a valid phone number and they are selling your phone number or calling you back later. Caller ID said Broomfield CO 3034695213
Caller ID said Broomfield, CO and looking for roofs to replace on my street, which she named in the call. Told her had mine replaced several years ago. Then continued to tell her had ins. co. out last year to check after major storm and all ok ~ before I finished, she apparently hung up ~ said her name was Michelle and didn't catch name of company she was calling for ~ she talked softly and i'm stuffed up from allergies right now ~ sorry ~
For some reason I've been getting various calls recently from various numbers, and most of them are the same, no one's there, it/they just hang up on me without a word.
