Does anyone have any resources on using Japanese in customer service situations? The more advanced, the better.

I’m taking on a new job at an Eikaiwa where I have to interview prospective kids students. I’ll speak to the kids in English, naturally, but be expected to communicate to the parents in Japanese. I also need to speak to customers more generally – rescheduling lessons, etc.

I believe my Japanese has been somewhat overestimated, although I did pass a written test involving Keigo. I’ve drilled everything in the Genki textbooks for a few years now so that it’s second nature, but beyond that, aside from my vocabulary (which is quite wide ranging), my Japanese is pretty sketchy.

In other words, I’m going to have to level up pretty radically.

I’ve searched for some courses, but I can’t find anything really fitting.

Does anyone have any advice?
