Worst Guest Services Department !!! Norweigian does not care about guest.

First many of the crew members I met were great. My room attendant was amazing. The reason for 1 star is for the worst customer service from Corporate Office to hotel director who does not need to a hotel director. First I had a issue with the travel agent company World Travel Holdings (represents all the airlines) who represent Norwegian cruise lines. I had an issue with my reservations. It a clearly a issue on there end and I have proof but no responsibility from them. They do not care about there customers. I tried to get the issue fixed before I left. No call or response. Now for the hotel director. One I was at the front desk at Halloween night talking to guest service agent and I ask him if he was the hotel director he looked at me and said nothing. All I want to say was hi. Go look at the video. Throughout the cruise he doesn't smile. I few issues with guest services. I wanted up grade my room and pay for it but they said no more rooms were available. What's funny is there were 2 room I was looking to up grade was empty on my floor throughout the cruise. I love when I can catch people in lies.  A few issues with my room. Guest Services called me back to make sure that issues got fixed. But the big issue I got back from a long day of excursion. I used the rest room and five minutes later I heard something in the bathroom. It was my toilet overflowing. I called guest services to let them know. I called few times even my room attendant called. It took 40 minutes for someone to get there. I took a video of the water overflowing.  It was my birthday I missed my dinner and had to take a shower with toilet water on the floor but what can you do. I tried to make the best of it and skipped my dinner specialty restaurant and had regular dinner. What is disturbing issue is that no one from guest services called my room to apologies for the issue or offer anything for the inconvenience. If I was the hotel director I would have called personally but maybe that just me. I guess you have to be in suites to get a phone call back but the little people just don't matter. I work in the hospitality industry and know how guest should be treated. One last thing is its amazing that certain people on the cruise get offered to stay on the cruise for amazing low price but other do not. That comes from the hotel director I could have stayed but if this is how guest are treated from Norwegian. All I wanted was the same offer as the other passengers to stay on onboard.
