Technically, the Room Type Guarantee only applies to rooms within North America for Gold-level members, so you wouldn't expect to receive compensation.

Did you specifically reserve a concierge-level room? If not, you could speak to the front desk about this. Also, mention the fact that you were shuttled around to different rooms, causing inconvenience.

As a Gold you would have had C-lounge access anyways.

I have had good experiences in the past with Ren Zurich staff, so I'm sure you'll have some positive response to your concerns.
