Caller asked for our owner or President of the company and gave a name that does not even match close to our President or CEO of the company.  She mentioned something about renewing a lease.

Called wanted the president, said she was a GSA contractor and wanted to know if we would like to do government work.  Hung up

This is a company which is soliciting clients interested in GSA contracts, most likely is mass-targeting companies (small businesses?) which have DUNS registrations.  The caller left voicemail, and seemed to be reading from a prepared script.

Called asking for our president (we only employ 3 people...) to talk about a government contract. I hung up on them. Lady calls RIGHT back to tell me IM RUDE. I could not believe that, you're bothering me at work but I'm the rude one...
