someone called almost 9pm and didn't leave a message

The number called, but no answer. When you dialed back there was a message of empty number. Take care of this number.

The number called but no answer everyday at 8:00 pm , sometime 9 pm, when you dialed back there was a message that the number you called have no sign.

It's about duct cleaning. Before i could finish say that we don't need that he (Shawn) hung up on me. I always try to be polite and treat others with respect. Being hung up on is rude and uncalled for.

Caller identified himself as "Dave" from Air Duct cleaning.  Hung up on me when I told him I was on the Do Not Call List.  Third call from this number in the last week.  When I called the number I got the message "this number is not in service, please hang up"
