KFC review: Drive through times and messed up order

I waited 25 minutes after i went through the drive through, They told me to wait outside in the parking lot they would bring my food. After waiting 25 minutes i went inside the kfc. I ordered 2 can dine for $9.99. One with regular mayo and one without, I ordered a big crunch combo wth regular mayo after waiting an additional 10 minutes they completed the order. I spoke with the manager in the store who had no clue on what she was doing. There was 5 other people waiting along period of time as well who were pretty upset. I drove home to stouffville and when I got there my order was not correct.The lettuce was brown the mayo was spicy on the chicken . I have ulcers and cannot handle spice. one of the chicken sandwiches was under cooked. I been a long time kfc customer i usually once a week however if this continues this no longer go and I definately wont go to the store in uxbridge again. They forgot to give me the receipt but my number is [protected]
