I've booked a wedding venue and signed a contract AND put a deposit down, my wedding coordinator called me and said someone booked that date before me and she was unaware. She has offered me a crepe station on the house for 4 dollars pp. I'm not sure if this is appropriate because she has also messed up a prior date giving me one price and then realizing it was Labor Day and tried to charge me more unless I changed the date. (She then proceeded to give me free up lighting which is values at $750) I took the offer Which prompted me to change it to this current date which is now taken

what is an appropriate reasonable amount of money or upgrade I should ask for ? Sorry if the post is confusing I'm writing from my iphone and a bit agitated.
