Our AC broke and they won't fix it

As the title says, our AC broke over a month ago. Two weeks ago they had a guy come in to fix it, but it still doesn't work. It's a consistent 85 degrees in here. The boh is cooler than the foh. We're all dying, it's so hot. Employees have brought in electric fans to try and help but they just move the hot air around. Customers are starting to complain, but nothing is being done. Our AC usually breaks every year but they get it fixed within a week, but this year they haven't and it's so bad. We all feel like we're going to pass out constantly. I don't know how customers are eating in this eat, it's miserable in here.

Just ranting pretty much but any advice is also appreciated!
