They call all the time, but hang up when no one answer and do not leave any message, nor say WHO they Are!  I refuse to answer any number without a name or knowing exactly who they are!

Same.  They suck.

Cold call wanting to set up a furnace maintenance appt. When I politely explained that we already have a contract w/ another company, the male caller called me a [***] several times and when I chuckled in response, he told me to f@&# off. Oh well... guess I won't be getting their info for possible future business or referrals.

Left message on the answering machine, asked for my husband and me by name, and then made fun of our last name.

Received call from this number on my cell phone. No message left.
