Huh?

My most recent call:

Me: Tech Support, this is Dave.
Caller: Hi Dave, is this Technical Support or the trade desk?
Me: Tech Support.
Caller: Ok, thanks! *click*

Hrm. Most folks get the name wrong(I've been called Wayne, James, Dale, and most often Dan), but he misses the tech support?

Which one of you is crank calling me?
