I had been getting calls from 781-339-9997 same as all others , no message, hang-up etc...... and it now appears that they have moved that number to 413-339-9997! Whistle sounds like a really good idea.

Have called several times. Finally answered, they asked for my husband, wouldn't leave a message just Hung up on me. Who is this??

Called last night didnt answer called again just now and hung up on me when I answered.  Attempted calling number back and unable to a ring or anything ...weird

yup! they called again. strange how the phone only rings twice before the answering machine picks up. usually it rings four times anyway. arfe they trying to controll the answering machines of the world now???

I answered and they wanted me to have them clean my furnace.
