Calls daily but leaves no message.

This is call that went to my mother who is 92 years old.  Two automated calls were made on July 18, 2010.

They call with no name on caller ID.  only a phone number.  Ask for someone who I don't even know.  Said their records showed I was related to the individual. Yeah, I know her...she is my ex-husband's now ex-wife, and there is no way on this earth she is related to me and I told the lady so; but she kept insisting I knew where to find her......Leave me out of her mess, it's bad enough I had to deal with her when my ex was married to her and my children had to put up with her mess

I called them back, got a lady on the phone who would not identify her company name or nature of their business if I was not the individual who could handle a matter associated with someone else.  I suspect they are a collection agency.
