CID just says Alert, don't know what that is referring too but, they could have displayed their full name. Putting bogus and/or incomplete  identity isn't going to get them anywhere.

Must be a new startup scammer, just got the call about a half hour ago

Just got a call from this number.  It said "SNFCONTR."  They left no message,  Must be a ROBO call.  However, there is no way I intended on answering.  Get a real job.

some message to talk to customer service abt medical device, press 1, so I press the 1 to play with them.  i am going to harass all these types if callers from now on.  the caller id says san francisco .well she calls me by name and I called this stupid foreigner every name in the book and she started crying/  she trying to sell medical alert bracelet for free for only $34.95 and supposedly 3000 dollars worth of coupons.  LOL.  I asked for her ssn b/c we are on the do not call register.  and of course she wouldn't give it to me and continued to read a script or play a tape one or the other.  I told her we are on the dnc register and she just screaming and yelling the script over and over wanting her $34.95. so I continued to call her lots of filthy names. she was sniffilig and crying b/c she didn't get to scam me. and told other people you could hear in the background what names I called her.  it was a real hoot.  I must have tied up their phones for 15 minutes.it's free you know, but it costs $34.95.  and the poor little foreignor started crying.  boo hoo. that was FUN

Just Blocked the number using my call blocker. Don't know how I ever lived without it. Since installing it in December 2014, I have blocked more numbers than I have accepted.  I can block up to 9,999 numbers. Bring em on scammers!
