I sailed on the Oasis of the Seas January 22 - 29, 2017. My suite was 8630. My cabin steward was Gusti. I left the ship on Sunday the 29th. When I unpacked on Monday I found that I had left my jewelry on the ship. Two long silver necklaces, one bronze chain with a diamond clasp, one pair of earrings, five thin bangle bracelets. I left the jewelry in the mirrored cabinet on the left side of the mirror on the second shelf from the bottom of the cabinet. I called RC immediately on Monday. They said they would get back to me in a few days. I was sure they would find it. She called me back a few days later and said they didn't find it. I asked her to check again. Asked her if anyone had actually contacted the housekeeping department on the ship. Maybe asked Gusti if he saw it. She said she would check again. A few days later, today, again she informed me that they did not find it. I asked to speak to someone else and she told me there is no one else. Apparently everyone in customer service is a supervisor and there is no one else in the company that has any interest in talking to unhappy customers. After some discussion about how my jewelry could have disappeared from that cabin she said she wasn't even sure the jewelry existed, essentially saying that I was lying. Sadly, I do not have her name. I was so angry I forgot to write it down! I am not new to Royal Caribbean. I achieved diamond status on this cruise. I would love to hear from someone at Royal Caribbean if anyone cares.
