Called and said he was from the Rocky Mountain Company and wanted to talk to me about a business matter, but refused to tell me what it was about.  Kept trying to get personal information out of me (Date of Birth/Address, etc).  I refused to give him any information until he told me what he was calling about.  The call came up as coming from Calhoun, GA.  I finally hung up on him when he wouldn't tell me anything else, but insisted to try and get personal information out of me.

A vague "business matter" usually references debt collection without actually using the words. This is done to avoid an easy FDCPA lawsuit for privacy breach.

Just called me and when I started asking them questions they hung up. I refused to give out personal information.
