performanmce called my house wanting personal information about me and would not tell me the nature of their business and asked me some questions that although they were incorrect made me realize the maybe ruling out info to narrow something down to me. icalled them from another phone and asked the nature of their business and i got a voicemail so i used another phone and called and when i asked the same question. the lady told me to givre her my account no. i said i dont have one and she said if i didnt have one she was going to disconnect me and she did. who are they?
