Called 4 times in a row, no message left

This woman called claiming she was an agent of some sort,  looking for someone with the same last name. She became agitated and rude. Finally, she hung up, because I kept asking what she wanted from me. Pain in the a@#.

Me too ... got a call today said it was Investigating Agency looking for my name from a former husband I had over 20 years ago!

some P.I. asked for _____  _____ and needed to speak to her urgently. I told him she moved out 2yrsago, this is an apartment building manager office. He asked where she moved to and i said i dont know, im hanging up now.

A woman called from LCS  and left a message wanting to talk to my ex-husband's brother stating he had an case pending in court and if he didn't call back he would waive his rights to an attorney. Sounds like a debt collector.
