Received a call the previous day with a similar number and same nearby town. I answered the call today and a very gruff-sounding man said “Mr. (Last Name)?” I only said “um” as if to ask him to repeat the name but immediate **** up. Tried calling both numbers. I got six rings then a recording stating “The person at extension 5 is on the phone.” Same message on 720-640-5428.
