an unprofessional sounding caller just called my employer regarding "additional client base", got my supervisor's name wrong (I said the person didn't work here), asked for the owner of the company, so I put the caller on hold. didn't give me enough information, so there's no way that the call would be transferred.

Same thing just happened when I asked what it was regarding they said "regarding SMS" and hung up.  Definitely bogus company.

called again today, months later. I asked for more information (or else I can't forward the call to my employer) and was laughed at. I also heard what sounded like somebody saying "what's up?". I hung up on them.

called and ignored.

called again
