called it back got a recording that they raise money for non-profit and political organizations, they do let you hit 0 and enter your number to remove it.
I also called this number and got the recording to have my number put on their do not call list. They came up as USOC on my caller ID - I do support the US Olympic committee but I do NOT want anyone calling me (ever!) at home about anything I support.
I was away when I got 5 calls from this number in a 9 day period. My husband did contribute to the USOC so it probably is them also. I don't pick up the telephone if I don't recognize the number especially with no name.
Received a call from this number. I didn't answer. They hung up without leaving a message. Caller I.D. showed: Salt Lake Ci UT. I am registered on the "do not call list".
