Got two calls from this number -- the first time back in March 2016, the second one just this afternoon today (9/12/2016). In both cases, the Caller ID showed up as "ASSIST 1-970-236-9187". And in both cases, the calls rolled thru to voice mail, and no message was ever left. The first time, I didn't bother with blocking the number. Now, after this second call, I am adding the number to my Call Block List.
