I hope the word "loving" was a slip of the pen, if not? As for calling revenue about unusual tax questions? I've found a few times that the person I talk to and the person i'm then put in touch with know nothing and aren't too interested in getting the appropriate information either. On the other hand, when the question is within their capabilities they'll do everything for you. I also found that if you ask them their name that it's a very good way of being helped.
