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

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

I am suspicious about why someone is calling my number and wanting to know about whether I have security around my home.

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.

Calls every day,hangs up before it goes to the last ring prior to the answering machine kicking in.If this is a legitimate call,they should leave a message like everyone else does,however since the calling party wishes not to,I'm left to believe the call is of dubious nature and refuse to answer.

somene is calling and not saying anything
