Rotten Wors

I bought a wors in that pick and pay and I realised when cooking it if it's rotten. When I took it back the manager John gave me a disgusting attitude as he said to the teller lady \give her another one\" without any apology. I am so angry. He doesn't have customer service skills that dude, I advise u to take him for the course. His so rude and unprofessional. I waisted my time and my petrol going there. I use this pick and pay daily pliz do something. I feel so disrespected by John as he just ignored me when was trying to talk to him and decided to make me a fool and make a phone call while was talking to him. "
