Late Night Service Battle

So i checked in today at 12:20am and as I got to my room it was a smoking room and im a non smoker, went to reception and was issued a different room. When I got to the room the key did not work and went to reception again to reprogram it. Went to my room again and the key still did not work. Eventually reception sent a security up to open the door for me only to find that the Aircon is not working and the room is extremely hot and maintenance is not available at this time. For the 5th time I went down and got issued another room only to find that room's Aircon not working too. Eventually I got a room who's Aircon was working and where I could eventually settle in. The time I got into my room was after 1am. So this took me about 40minutes to actually get into a room and rest after a long day at work. I find service like this really pathetic, the person who assisted me name is Precious although she was very helpful and could see I was irritated was actually embarrassed and couldn't apologise enough. I know it's not her fault because her service was good but the overall service regarding the rooms is pathetic especially when checking in at that time and have issues.
