I suggest that you work with H on a mutual exchange where he opens up your access to the hotel rewards account. We encourage newbies to post draft emails here and we can support you with feedback so it is in line with KISS and STFU principles. It is not that you cannot do them yourself...it is a way for you to learn how to keep them short, concise, and without snarky comments. After a while, you will be able to do them yourself.
We see far too many times here in DB that the WAS write long responses that are not helpful and usually blows up things.
