Calling about someone who doesn't live with me.

They call asking for someone saying I was a contact number, and when you try to ask why they are calling they get really rude,

Received strange call from this number, woman said that Chris Adams would like to speak to me and take as statement for their file. They refused to identify the company calling or the subject of the call. I asked for call back numbers and got:  877-243-5126 and local number 864-990-5353 which appears to be in Greenville, SC. I saw no reason to take the call or return their call.
