Sprint was calling my house every day for about 3 months asking for someone I didn't know. I told them that I don't know this person, and asked them to stop calling.
I did finally get them to stop calling. A rep called while my daughter was napping, and woke her up. I told her AGAIN that this person can't be reached here. I told her that if Sprint called me again, I would file a law suit.
She then told me, "I'm sorry, there's nothing I can do. Your number is in our computer. We can't take it out until we get in contact w (lady they were looking for). I then informed her that I have a phone recorder, and I will use it for my law suit.
I then asked her to repeat what she told me, and like magic!!!
She was able to remove my number. I never got a call again :D
