Bad Customer Experience

During the hour of my lunch I went to pnp across my work. I ordered some of there cheesy nuggets which I do on a regular basis. Upon reaching back to work I opened the pack of nuggets and it was rock hard and dry as desert. I can differentiate between the two as I buy it everyday. I then took it back to the returns and asked to speak to a manager. The assistant and the manager were speaking to each other and not speaking to me the customer. I have NOT received an APOLOGY for the inconvenience they caused me and selling me food that is of not good quality. Apologizing to the customer is suppose to be the first and last words uttered. The manager and the assistant had no management s****s, I wasn't looked info my face once, no greeting nothing. Why are people not checking the quality of the food before its being sold to there customers.
