Consistent Poor Customer Service at KFC Grayston Drive

I hate complaining but sometimes I am forced to do it because of the bad behavior that doesn’t seem to change, I don’t remember visiting KFC Grayston drive and leaving happy like it happens with all the other KFC’s, it’s like the staff there hate what they are doing or they are bitter about something, this morning I went to buy streetwise two pap at Grayston Drive and I used a drive through option, one of the ladies that was assisting me to pay shouted at me telling me to move my car, and we had a very heated argument, and I think she was giving me that attitude because I told them that their drive through intercom sounds very soft, and I was being honest, however I was punished for raising a service issue, please ask the management at KFC Grayston Drive to train their staff, especially when it comes to customer service.
