Disappointing food and service!

Very disappointed in KFC Hercules, and this is not the first time. We waited over an hour for two regular twisters on a Sunday afternoon. When we eventually got the food we were very disgusted with what we got. The lettuce looked like it was left out in the sun for days and the chicken was soggy too. We took the twisters back and spoke to the manager who agreed to replace them, but I really don't even want to eat it because I am terrified that I am going to end up with food poisoning as I am now questioning the quality of the products used at this KFC. I really don't understand how this particular branch is still open.
