Who called from 2173642526

I called them back just now and left a message saying a lot of people on the internet really wanted them to stop calling, etc. :D

who owns this phone number? received missed call at 2 am on my cell

i got a call at 5 am an no one answered

I got a one-ring phone call at 1:23 am recently.
They hung up immediately.
I have no knowledge of who or what made the call.
I was not pleased.

I have found out through the internet that the number is apparently out of Buffalo, Illinois, USA.

I used call return three times to make sure I got the correct number.

I received two calls on my cell phone from 217-364-2526 - both the same night.  One was at 4:02 am and then again at 5:11 am.  I thought that I could hear someone on the other end but they hung up after I asked "who are you trying to reach?" several times.  I would like to know who this is and where they got my number from.
