Rewards redemption robo call. Amazing how when you call the number back your presented with two options 1) redeem the $100 voucher "reward" and your hit with a "sorry the number you have dialed is not in service" and 2) not interested and you get "thank you for your time you will not be contacted again" [bear in mind I have caller ID blocked so I should show up as unknown or private number to them. It probably does nothing but I blocked them in Google Voice and the Android phone/dialer app.

I got a call from this number at 1:20pm.  Didn't answer it though.  Certain call numbers like this can actually trace your signal and get information that way.  I just don't risk it hardly at all with any of these types of numbers.

Rang once and then hung up.  This was on my cell phone which is on the do not call list for all the good that it does.

came up unknown caller phone rang one time. added number to block list
