The level of poor service here is disgusting

The level of poor service here is disgusting. At one point I waited 1 hour 39 min on a drive through had to get off the car and go inside to scream for my order.if it's not their ice cream machine or ticket issuing machine that is not working. You will be told to wait for the meat in a process of hurrying the cooking as people are piling up the meat is served not well cooked. I don't know how many times I have had asked for the manager and complain about poor service maybe because they don't have competition. I then decide to use online to see if maybe I will be served faster. I placed an order pay online. 15 min later I got there my slip had not even attended too. I was still being asked my name and if I paid. When I thought that was not enough. I was asked to wait 7 minutes for the meat that 7 minutes turned into 20 minutes which I was served half cooked meat after I demanded a refund. I dont know why are they always short staffed when they are soo busy. Another kfc opening there will definitely give them a wakeup call
