Expired rotten crumble chicken from Checkers

I went and bought groceries, one of their store prepared crumbled chicken fillet was rotten. This is in their meat section. I called and complained, they asked me to e-mail and send pictures. I responded on e-mail with pictures and they simply ignore my complain. So it is ok for checkers to sell expired rotten food and they brush this off when i complain as a customer. Be careful when you buy meat, they don't seem to care about their customers or what they put on shelves.
