One other option might have been making the phone call from inside Gmail via your computer.

I've personally learned the hard reality that most people currently alive cannot use email correctly and therefore demand that everyone they do business with provide phone support. Because of this, the path of least resistance is to just be like them and get used to calling when you need something resolved. (And the reality is, it's faster for the people at the other end, which is why it persists.)
