Called 4-12-17 at 9:43 a.m. CID showed Sedalia CO. No message was left. This seems to be our monthly call from "Sedalia CO" that we never answer and no message is ever left.  The only difference is the number. On 2-6-17 and 3-1-17 Sedalia CO called from 303-351-0489, today it was from 720-770-2718.  What will it be next month????
