Calls from this number were identified by the caller in such a way that I could not understand the source, a company that wanted to confirm my email address to send me white papers because the company I work for has some finance & accounting work. She was working off an old list of names because my company name she used was from before a name change for the firm. She said she wasn't selling anything. I did not confirm the email address, but she did have a valid one.
Fishing for good email addresses and phone #'s.
