I keep getting a call from a bill collector for my mother and she has NEVER lived with me. I tell this lady that she doesnt live here and never has and her response to me is i will keep calling this number and bugging you until i get her number then. I have told her not to call my home anymore and she continues. When itry to call the number back its ALWYS busy no matter what day or time that i call. What can i do?
