next cruise

Next cruise manager went ballistic when we questioned policy around why he allowed non-reservation guest to book but would not take us earlier in day. We left and returned at time of our appointment and he said he would not provide service. He did in very agressive manner in front of other guest. I asked to see his manager. He stated he was in charge and called secuty to have us leave. This action cauzed us to loose additional freeplay benefi from casino voucher. He made up stories about us breaking in line and not respecting him. Absolutely not true. Went to customer service and they stated no control over Nextcruise manager. Offered us some forn we could submir even though the CS tean had documented. Does anyone have suggestions how to directlt handle with Nextcruise mabagemwnt? No phone number availavle.
