This is a con... they want to know if you have a security system in place etc so they can rob your house..Do not speak to them at all. Suggest you go to the nearest police station and report this incident with the phnoe number so you are covered in case of a situation,

Asian sounding caller wanted to know about my security. Told him of the no call list kept insisting I was not on his list. Told him to delete me from his calls very argumentative repeating my security system. Again told him to delete me from his call list or I would report him to the national do not call list. Kept arguing about my security system. Hung up on him before telling him that I would report a complaint about him which I am just about to do. The best thing to do is to get as much information and then lodge a formal complaint as he just wants to wear you down and argue.

same kind of call did not answer myself answering party when asked about security said not interested, woman caller this time, unfortunately did verify name of houshold, will let local police know concerns

Multiple calls from this number.Never leaves a message.If I happen to be on the phone then my cell starts ringing showing "Blocked"number.Call back does not work always busy.What can we do about this? Its quite frustrating

This person has called me twice now and when i try to call back, it's a busy line.

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!
