Creative Caterers at Glendoveers

I'm gonna keep this short but I do have a much more detailed post as well as receipts. I had my wedding on 6.22.24 and these were my caterers. From the very first meeting with them I had a custom menu. Which was gone over more than once leading up to my event. I was assured it was fine. On the day of my wedding I was missing appetizers and my dinners were not the custom options I had worked out with them. When I requested a PARTIAL refund (because the bar was fine. I'm not going to unreasonably request a full refund) they said they wouldn't because it wasn't their fault I received the wrong food. It was their employees fault because she put the custom notes in the wrong spot. So somehow they are not responsible for their employees. In addition, just be warned that they told me it's their policy not to refund overpayment. I overpaid by about $250 based on my invoice total and was told they won't give it back, in addition to not giving me a refund for messing up my menu. I gave them a chance to work this out privately but they refused to work with me, so here I am in the court of public opinion. Here's what I know their response to this is going to be, because they told me already. They said they don't owe me money because (besides not being responsible for their employees mistakes) I underpaid already. They think I underpaid because according to them the minimum charge for the RMSC is 100 people, which I was never told, and in fact, at my very first meeting I told them my guest count was 85 and they said okay that works. So I'm not sure how I underpaid when i signed a contract they made for my event. If they forgot to charge, that doesn't mean they can just freestyle my menu into something I didn't want with absolutely no communication about it. Aside from all this, the food tasted like a salt-free reheated frozen dinner.
