How to approach disappointing vendor over wedding set design disappointment?

I’m paying a professional haunted house group $11k to create custom haunted games and set design/photo booths for our Halloween wedding (contract specifies materials, labor, setup, etc). It’s one month out and we have paid 70% and so far we have gotten nothing but shoddy communication and pushback for everything we are requesting. Nothing has been made or even planned. They are trying to push what they already have premade on us and essentially demanding more money for anything that isnt premade. I.e. Suggesting skeleton ring toss and spooky corn hole (premade, and not at all what we were expecting from a professional prop maker), while immediately refusing to even entertain our ideas (I.e. brain toss, human operation, etc) we are being sent links for a special prop that costs $1,000+ extra on top of our $11k anytime we make a custom request. I do know now the business is suffering financially, and seems as though they are using us to fund their recovery, pay for games and sets that THEY WANT for their business and they simply don’t have the time/money to fulfill their promises to us. I’ve lost confidence in this company and would prefer to ask for money back and go with someone else.


I am leaving out the more obvious breach of contract items (since this is the easy part to dispute) but for example, she claims contract specifies 2 sets and 3 custom games and then arbitrarily decides what is a game and what is a set to fit items she already has. Contract clearly says 3 and 3 of each and custom with Materials/labor/design to fit our vision.
Anyone in similar boat? How do you approach and do you consider legal action? They have delivered nothing to us not even an original concept since the $7k was spent, I wouldn’t feel bad about asking for it all back.
