I see. But this sounds like his/her office made a mistake in calculating the fee, but let's say this far away from "ripping off" and can be cleared in one telephone call.
That was not my impression. I asked them about the fee, they claimed that it's legal/required by law. Then I asked them again (in a more detailed manner, i.e. explaining my thinking why there shouldn't be a fee), they still upheld that it's legal, and then I send them the court rulings and suddenly they had "forgotten" about that.
