Circle K complaint: Bad milk wrong ciggarettes

I bought sum milk the 2.09 one and asked for silver 100 edgefield cigarettes. I also purchased a candy bar and apple juice. The attendant put my things in the grey bag , totaled it and I paid in cash. When i got un my car i reached in bag and got my cigs iut to smoke one. She gave me the gold 100’s. Not silver. So i went back in to swap out to silver and she refused to exchange them. The manager came up and refused as well and told me to leave the store as things were begining to heat up. I did and was very agitated. Went to another store and purchased the right ones. BUT THAT WAS NOT the end. Later that night i was eating the candy bar and opened the milk and it was disgusting spoiled. Next morning stopped by to exchange it and low and behold was told we can not swap it out because u opened it. I mean come on. Us this the education level if all their employees?
