Spammers!  My phone is on a do not call list already.   They call and hang up continually

call your phone company and complain.  if enough of us complain, they just might make a
free call blocking system that works.  my cell phone has this.

Called on 1/20/2015 no message and it looks like a robot program to see if the number is active or if someone answer this is regular from companies that have your info and they sell it to telemarketers do not answer or block this number...

I felt it was my duty to mess with an unknown number so i answered and amazingly enough it was a boiler room trying to lower my credit card rate (with a really broken Indian accent). i asked him "which card"? He told me "the card with the highest rate". "You should know which card as you are trying to lower my interest rate". I had this dood talking to himself when i finished with him..............endo convo....now black listed (AMF and he can go on to his next victim)
