received 14 calls no message left when I tried to return the call the line rings busy

i have been recieving calls from them every 10-20 minutes for the last 2 hours. They leave no message.

Non stop calls no message from this number left. Googled it and saw its an insurgence company.

970-344-3133
Called twice within 40 minutes on 3-20-13 and left no message either time. Number from Berthoud, Co? This is the first of 2 different numbers on the same day, from "Berthoud" according to whitepages.com (for real? not sure...), called more than once, left no message on any call. Don't know anyone from there. However I did post an internet request for an insurance estimate for a roof. This may be a call related to that.

Same with me -- I filled out a request for an auto insurance quote and the ad specifically said I had to enter my phone number for verification purposes, but "NO ONE WILL CALL YOU."  That's the only reason I entered it -- and now the calls won't stop, nor will the emails.  I had 78 emails from car insurance companies this morning!  UGH -- will never do that again.  And, on top of it all, not one of them could save me any money over what I'm paying now.
