My caller ID showed this number. and they left a voicemail of just hang up

This number has been calling me for days, hanging up, leaving no message.  I called it back and it is One Hour Air-Conditioning.  I did not call them or need a/c so it must be a sales call or wrong number.

They are now calling themselves A-1 Heating and AC. I answered because I am awaiting another local business to show up at my house.

Guy identified himself as Mike. I told him to please remove me from their fall list, he hung up!

I called them back and got VM. I left them a message informing them if they called my cell phone again I would take them to Small Claims Court!

They want to be rude, I can play that game. I was very polite!

Just got that call today from the same exact number.
