Scammer selling fake security systems and asking for ur credit card

Phone rings, you answer, there's no one there.  No script, no sound, no nothing.  If you call the number back, you get an automated voice response system where the only option is to "press 1 to be placed on a do not call list".  No other information is given.  Pressing "1", the recording will tell you to "please allow up to 48 business hours for your request to be processed"  (That's 8 days.)

same as batman.  phone rang, upon pick up there was no answer, no sound.  I just put the number in auto reject. I did not call back

Got a call on my cell phone asking me to install a GE Home security system. I added it to my reject list.

Missed this call, no voicemail, didn't call it back after reading these comments.
