Kentucky Fried Chicken [KFC] / my check

So I was just rescently working at KFC here in DeFuniak springs FL 32433 well for some reason they are not wanting to pay me my check n I have returned my uniform to them already n everything. They keep saying it went to another office or they just don't have it .. and also from my understanding it's against regulations for a restaurant to run without AC well there's have been out for I know of a month now n it's really hot in there
