You can call them at 801-373-7735. Use Option 9 for the Name directory (run a web search to locate the officials - most are in LinkedIn).

The company keeps calling - multiple times a day, and as late as 8:47 pm. When I answer, the line goes dead. I don't know if the computer caller is getting ahead of its representatives, of if the company is profiling (to see if I'll call back, etc). But I have been inconvenience many times as I chase for a phone with a dead line.

I've read that they call to conduct political push/pull surveys (not real surveys, but 'surveys' intended to distort the views and actions of an opponent while making the politician that paid for the survey look good).
