A professional-sounding man who never identifies himself calls and leaves a message for me to call him back but never leaves his name or company. The second time he called, his message said that someone told him to call me and gave a name of someone I'd never heard of before. He's calling my work number and I get a LOT of solicitations so I won't call him back until he leave a message as to who he is and what he's calling for.
Exact same experience as H above me. Has left at least 15 voice mails, has never once said the company he represents or why he is calling. I get a lot of cold calls so I will not be calling back until he leaves more information.
