Who called from 5802715562

Here at work three of us got same call one after another then our lan lines went dead.

Had the same thing this morning. Called back and got message OK20 (disconected) from US Cellular.

Says they are selling security system - SCAM - I've reported but still get the calls!  I called # got the "out of order"  Then I get a call from 956-360-4000 with "John" - Asian voice - thanking me for my interest.  I ask for the name of the co and the owner and they hang-up on me.
SCAM!!!!!!

Just received call and it was for an offer of a 1500.00 free security system.  A recording with a number to call back

I received a call from this number today. They left no message on my voice mail. I tried to call the number back several times and got a message that said Oklahoma message 20 the cellular customers number was no longer in service. I wish people would stop doing this crap.
