If you think that was bad then you definitely don't want to hear some of my stories!
Honestly, a few simple things could have been done to ease your mind right away. #1 - When you call from your in-room phone you don't get the front desk, it is a call center in another city. They have no idea what you're talking about. #2 - Luggage being delivered to your first room was related to you refusing the room you were assigned, a decision you made on your own. So I wouldn't blame bell services for that. When you arrived at the second room you should have immediately called the bell desk to tell them you had a new room so they would know where to bring the luggage. Those poor guys are running around sweating and working like dogs, they can't be mind readers too. After 15 minutes or so the first thing that would have popped in my mind was that my luggage was in my assigned room. #3 - Those calls from Magical Express come no matter what. I do split stays almost every single time I go to WDW and they always call me and leave an envelope on the door the day I switch reservations, every single time. All you had to do was throw it in the trash and delete the message. #4 - The broken knob was a maintenance issue, any time you have something like that pick up the phone and push the housekeeping/maintenance button. They will put you on the schedule. Obviously a missing knob isn't going to rank as important as rooms where the A/C won't come on or a room (like I had 2 years ago) where the toilet water was leaking continuously and running out on the floor everywhere. They deal with issues in order of importance. Patience was all that was needed there. #5 - Trash outside on or near the patio accumulates daily I'm sure, heck probably hourly. I have seen people put down empty beer bottles and drinks walking back from Epcot, the mousekeepers can't stand vigil outside your room watching for every person who throws down a scrap of paper. #6 - Paying the taxes on the complementary room makes perfect sense to me. The same goes for free flights, you always have to pay the tax. Heck if you win a car on The Price is Right you'll still have to pay the taxes. I'm actually surprised they waived that, I doubt any other hotel besides Disney would have.
