Raw food and disgusting service

I am disgusted by the service i received Fr m brocka as a regular customer,i ordered a burger and it wasn't just raw but the blood was literally running out of the patty,i called the waiter to request to speak to the manager,the manager then said Myself and my girlfriend can come for a free meal which kinda made me feel a bit better,however a month later when we came for the free meal,my first bite into the new burger was more raw than the first time,i called the waiter and said,we were told to come for a free meal because the burger was Raw and now we sitting with another burger wich was that 6 sliders all raw..the manager had the audacity to tell me,its a free meal, unfortunately we cant tell you guys to come have another free meal,I haven't even started eating just took 1 bite..and noticed that the patty is once again raw with blood gushing out of it,i am very disappointed!!i highly recommend that you stay away from this restaurant.
