unwanted call

Rcvd missed call everyday for 5 days now at 8:30 AM from Utah listing because I work nights and am asleep at that time of mrng.  I call back and get a busy signal.  Today, I was awake and answered and no one said anything.  I read the above comments of similar calls from this number and have now blocked the number. Thanks for everyone's input so I can be assured I'm not blocking or missing an important call from the VA or a job offer from an HR office based out of Utah.

Called twice at the same time. The person hung up.

Calls every morning at 8:30am. Reading above posts I will not answer. Also, the number it calls is my business line.
