I keep getting calls from this number 1-636-724-5911 as well, like at least once every couple weeks.  I try to call the number back and a recording says the number has been disconnected.  Weird!!!!

they just called me too!!! and i said hello like 3 times and they said 'hello' and it was all static....what the heck!

Don't have the Go phone have Tmobile and in a contract with lots of minutes left and still keep getting calls??  I think people on land lines get the calls too.

Called and said "uh hi" and then hung up. I'm in Springfield, MO.

I answered and said hello then the pause that tells me it''s an auto dialer, a male voice said hello and hung up. I've heard people that do this are just confirming your phone number is a valid working number answered by a human. Then they sell the list to telemarketers. I know I should just let the machine pick it up when I don't recognize who's calling but sometimes I'm in the mood to hang up on them.
