Wedding Vendor Issues Post Wedding

Hello all! I got married last week and need some feedback on how I manage a tough conversation with my florist. We didn't have a formal contract but we had an email conversation with the total price ($2,500) and what was included : 22 dining room centerpieces, 10 cocktail centerpieces, 96 votive, 9 bouquets, 2 corsages and 3 boutonnieres.
I provided black lanterns for additional decorations. She asked if I wanted her to decorate the lanterns and I said repeatedly no, to have separate centerpieces in gold vases for the tables.
On the big day, I found out that she completely forgot the corsages, made extra boutonnieres, and added one piece of greenery and two small flowers for each lantern with no 22 centerpieces.
I want at least a partial refund if possible since we were missing 22 centerpieces and corsages but not sure the right way to go about it. Flowers weren't critical to me but I don't think I got my money's worth. She has great reviews and I was extremely clear on email - I outlined the needs in 5 separate emails plus a text the day before. She completed set up after I had left for the ceremony so I didn't really notice until the wedding and after when she had already gone.
Any advice?
