There are ways to let a hotel know of an issue without coming across as a complainer or a douche. As others have said, do it in a civil manner without raising voice or coming across bad. It is very easy to say OK, no problem, then just take your business to another hotel in the same chain or not.
And to OP, just because you are lifetime status does not mean you are bound to stay at only that chain. In fact, it is an opportunity to try another chain without losing your status in the chain you have lifetime status in.
