Rotten Meat

I would like to express my disappointment with purchasing meat from your Phoenix store on the morning of the 27th May. I purchased a pack of half lamb which was placed in your cooler. I was on holiday, taking my family for a break in Port Edward, I stopped to buy your meat and when I had gotten home that morning to prepare the meat for the trip to Port Edward, I was really disappointed and upset that the meat was so slimy, smelled really bad, the color of the meat was brown and looked as if it was sitting in the back of your shop for such a long while and I was the "lucky" person that purchased it. I would like to get in touch with management or point me to the right person to speak to about my ordeal. Please can someone respond asap?
