Two calls from this number when I tried to call back the number was always busy! Glad to have found this site to report and find out what the number is used for.
I received a call from 406-974-6311 twice. when I tried to call back it is "Busy Circuit" type busy signal. Thanks to this site it was probable a scam selling type call.
After they called me four times in a row, and I googled and saw all these notes, I just simply "blocked" the caller. I know it won't stop all spammers, but it will this one!
