Either StarHot rates are unconfirmed, and a hotel can cancel them, or they're not.
I'd talk to HR to find out. And if they can't be cancelled, no doubt someone up the food chain can help.
Either eay, I suggest you avoid posting about this on a public bulletin board, since I'm guessing it'll be particularly displeasing for your employer.
Annoying? Yes, incredibly.
Worth job-related discipline? Probably not.
Best,
