Got called three days in a row from this same number.  When I answer there is no one there and then the line goes dead. Tried to call back to get them to stop calling.  Phone rings and rings then disconnects.

this nbr started calling again. No Answer at all.

Someone just called very rude and starting swearing and acting stupid.

If you tell him you have security already he says I know and would like to sell you more hidden cameras. Then I hung up.

same number keeps calling...one time they said they did duct cleaning...other times its security systems.  In other words they just want to get into your home, learn the layout, then rob you at a later date!  Bastards!
