Called my cell showing "United States" so did not answer and they did not leave an message.

Be careful with this one, and all like them!  Always tell them you have an alarm! When they ask how much you pay for monitoring, tell them "$15/mo Fire, Police & Water" they'll take you off the list.

Wireless systems by GE are the current teaser -- but that's all they are is teasers. The call is solely to obtain your schedule *if they learn you don't have a currently monitored system* they are *VERY* interested to get your address and schedule an appointment that never comes!  It's the times you *WON'T* schedule which they are after -- NO ALARM = BURGLAR FRIENDLY --

Of course you'll get a call from another 'Security Company' -- Lather Rinse & Repeat

Called and started dropping the F-bomb "don't you F****in hang up"

so I hung up and Blocked the number

These folks won't quit.  Automated recorded message trying to sell alarm system.  Miserable S.O.B.s!!!  Left no name of company.  Scum bags!!!

These dirty scumbags are breaking the law.  they call from different numbers, use different company names, don't follow the do not call laws....
