I am getting calls for a person who was my roommate 25 years ago!

Nelson Watson Assoc. contacted me and my elderly parents about her! I've had nothing to do with this person since1988. At one time had a restraining order against her. It was a shock to hear her name mentioned in a voice mail. I called the number they left and demanded and explanation as to why I am being contacted about this person. I got another call today (checked my caller id) but they left no message.

Any suggestions as to how to get the calls to stop and any idea how they would have found me? I am married now and listed under my married name. I hate they called my parents. The whole situation makes me very scared and nervous. Should I check my credit report?

Thank you for your help.
