1) Use w w w(dot)whitepages(dot) com to find the office that is calling you - the state & City. Use your caller-id to get their real number!
2) Go to w w w(dot)westassetmanagement(dot) com
click on work for us (what a joke!) and then click the locations button. You will see a list of all their offices.
3) send them a certified letter, return receipt to stop calling you
4) save the receipt & sue them for every call they make after that!
I had to call the police today to stop repeated calls to my home for a bill that is not even mine!
