Since Dec. 2004, I keep getting this woman leaving a Voice Mail for me, thinking I am some family member. Now, my Voice Mail announces my first name and a custom message, but I guess she's not getting the hint. I even called back once after about 10 calls (after blocking my number) and telling her that she had the wrong number. She argued that she didn't ever call anyone who had a cell phone.

Is there any way to block this caller, assuming the number she leaves is the number she's calling from?

And is there any way to find out the numbers of people who have called Voice Mail? This is annoying in people will leave messages and say "call me" when they are not in my cell phone book and I'm away from home (business calls, not personal)...
