Calls several times. No message. Called number and person refuses to identify themselves. Number shows as a residential landline in Wayland Michigan.

This person has called me on 07/22/2008 at 4:39pm, I called back and a lady answered said "bueno", then I told her someone from this number called me and I was returning their call, she hung up on me. I called back and the this time it "sounded" as though she said just the letter w.
So I just hung up. lol
 Not sure if it has to do with my internet dial-up service, which is called dialupfree of Michigan. My access number is from Wayland Michigan.

This lady continues to call my house all hours throughout the day letting it ring anywhere from a half a ring to three rings.
I have called AT&T annoyance and next the police if thats what it takes to make it CEASE!

Calls cellphone several times and never leaves a message. Called and the person refused to identify themselves to me. 269-509-4895 shows as a residential landline in Wayland Michigan but that's all the information I could get doing a search.

What can I do to stop this harrassment?

This person calls our house 1-3 times a day.. its getting very old..
they don;t want to identify themselves so I know they are up to something they don't ask for anyone either they just say hello.. neither my son or daughter knows who it is..(i thought it might have been one of their friends).. I do believe the call is from Wayland Michigan and my family doesnt know anybody feom there..

please stop the harrassment.. Wht can i do to stop it??
