Worst service ever

I requested a special of 4 rib burgers on the special for 169 the cashier charged us 227 and only gave us 3 burger. They literally pushed us put the shop as we was waiting for our food. When i asked to change the order to what i wanted they say no they cant do it . I have never reverted such terrible service i have never been told i can not change an order . I have never received such bad service in my life will never come back here
