If the emcee is temporarily changed, it is necessary to explain the reasons clearly and get your consent before doing it, otherwise the wedding company will be irresponsible. There will inevitably be some small mistakes in domestic weddings, but playing with the wrong wedding photos will be more serious.
Besides, a wedding is a happy event. If you can make concessions to each other, then make concessions. There is no point in going to court for these things. Ask them to give you a discount. Don't let small things make your wedding unhappy.
