303-647-5399

This number calls me at least every other day. When I pick up there is no one on the other end, and it hangs up on me seconds later.

Received calls two days in a row. Caller ID says "Onstar." I ignored it the first day, but the same caller from my area code called the next AM and so I thought it might be someone calling from their OnStar enabled car, so I answered. Thirty seconds of "hellos" from me and silence in return.
