Raw food and ******

was store in table view few days ago. I was there with my father. We had 2 xL Mochas to drink. 2 eat my father had the steak, egg n chips and I myself had the double bacon cheeseburger. To start off with the compliment out the mocha, the milk was off and the chocolate wasn't even added to it so basically we ended up with a disgusting Americano. My father's steak, was meant to be well done, instead it was completely rare and the chips on both meals was still hard and 80% raw. Moving to my burger, the patties wasn't done right, the blood of the meat was still running through the patties, it was absolutely disgusting. We asked for the manger but instead we got told the manager is busy and can not come see to us, our waiter was extremely rude and ****** towards my father. How can you have staff like this and still operate a restaurant. Does your staff not know how to fry a burger patty or a steak, do they not know how to make a coffee? Thankfully none of us is sick but this is disgusting. We actually are completely revolted by this service and the quality of the food. I am a member of your app, I couldn't even scan the slip on my app it didn't allow me to. Which is okay but the service and quality is absolutely revolting. Please tell me how to handle this and sort the matter out as R446.00 is a lot of money to spend on food that's so disgusting and no staff that wants to assist. As I actually would love to take this matter further, due to raw meat and sourness someone can end up extremely sick. The franchise Manager is the only one with customer service and respect. However the customer service office emails and says one thing and says they been instructed to do something by the franchise Manager, then they change the story and make up stories to not do their job. As much as I love bootlegger, stay away from beach front , blouberg branch.
