They keep calling even though they don't speak anything. They keep silent. It is a spam.

Just got this stupid call on my caller ID.  When I called back, I got a stupid pre-recorded message saying:  "We're sorry, no one accept your call, please try again later."  FKN IDIOTS.

they call me 3-4times for a week

I got calls 6 times at Saturday night. They sell ADT Alarm System.

I finally got fed up and picked up the call and SHOUTed at the top of lungs...


"WHAT????????"

and hung up.

I didn't get another call that day.

I got a call from this number 626-701-0136; I called back but always "circuit busy; please call another time", I grew suspicious and googled here and read your comments. Now realized it's a telemarketer for alarm systems. Thank you and really appreciate your reports of same experience. I now assign to this phone number a ringtone of "silent" on my phone, so it will never ring again.

Got two calls in last two weeks. Told him to remove my number from their calling list first time they called me. He said OK. But now another agent calls me. annoying.

Even if I said i don't need alam systems many times,
They keep calling. I save as Junk Call try not to answer the phone

during the last two month  calls randomly 5 times aday and sale product alarm system even I say NO.we need sue him

calls randomly 6 times aday and leaves no message at all whatsoever
