Scammers trying to sell fake Security Systems.  They are phishing for your credit card number and personal information.  Tell them nothing.

Didn't answer but when I tried to call back, says you can't call the number.

Just received a call from this number on my cell phone.
Didn't answer it & I blocked the phone number from calling me again.

After a bad night with my low back hurting badly, little sleep,@ 8:31 AM phone rings & woke me. I said Hello.He said How r u doing? Not well. GOOD ! We are giving away free security systems,r u the homeowner?Yes,& I own this phone,don't call back,DO U GET IT? He hung up!
