called my office phone left voice mail XXXX/XXXX/15. 
I asked them to send letter in the mail not call my office. 
They are trying to threaten they will take legal action on a debtthat the statute of limitations has expired 3 years ago. 
They said we do n't care about the law we will collect from youand sue you. I would like to let them know they can not sue mefor the debt bylaw or report it to XXXX, XXXX, XXXX. 
I know my rights.
