called my land line and no answer to my "hello".  WTF

This number called my cell phone and did not leave a message - number will be blocked.

Message said was "united edm air", something like that... Caller knew my last name and used it in the message.

This number called my DNC landline. I answered and there was silence on the other end. This number will be added to my blocked list.

Said it was time for my annual heating checking I said I am busy and requested call back number. He gave me 925-475-9873 which is Mike's cell phone. This time he said his company is The Furnace Experts. So give him a call and say hi, anytime, day or night.
