Hi cscvp, welcome to Cruise-Chat! I assume you spoke to the folks at Princess. Did you notice this before or after you debarked? If it was after, you can call the main Princess number and they can take the report.
I removed your email address for your protection and sent you a private message. I doubt seriously that anyone on the board would have any information, but you never know. Someone may have been on your cruise and remember seeing it. What was your sailing date?
