They called me around 5 times already in the period of month. When I pick up, they hang.

called at 4PM 5/5/15

Rip off scam

Blocked the number via android app.  Calls on average 3 times a day....

Automated call asking to "give me a free alarm system."

Asked to be removed multiple times from calling list. Bordering on harassment...

This number does not leave a message when you miss the call. The caller ID says name not found. Also if you try to call them back you get a messed up busy signal. If you answer they do not answer back they just hang up. Becarefull, this is either a scam or they are fishing for private info. If anyone can find out more about this company let me know.  I hope this helps you out.  Thanks
