Wingstop

My husband and I ordered some wings to eat at home during a football game. Well we had already eaten a few when my husband found a hair in his food. I through the rest of the wings in the bag and he ended up throwing up inside the bag. I called wing stop and they said k needed to take all the wings back. I explained that he threw up in the bag and the owner told the assistant to tell me they would only replace what I took back! I did not want any more wings with hair!!! The owner would not refund me my money and only gave me the number for corporate. The assistant said "I don't know how a hair got In the wings cause none of the cooks have hair" I said so your cooks are bald ? And she laughed and said "no", obviously she is not fit to be the assistant supervisor. I don't mind taking the wings back even with the vomit on them, but I want a refund not more wings!
