I needed to use the contact form to send my complaint about Sofitel NY. Really not easy to find. You really have the feeling that they want to discourage any contact with CS.
Once I found it, all the personal info were pre-filled and greyed-out meaning that you can't change them. Not a problem in principle, but in my case, it was all my professional info that were filled and not my personal ones despite my profile says that personal address/email/phone are the one to be used by default.
