Airwalk

I bought a schoolbag for my son at the end of August at Kmart. The schoolbag’s zipper broke the second week of school. I went back today to return it and Kmart has a 30 day return policy. I am upset since I had to buy another schoolbag for my son and never got my money back from Kmart. I have two young boys and I to buy schoolbags every year for them. I am mad that the bag broke so soon, really. I am really disappointed. I have bought Airwalk schoolbags before and they were fine. I would like a refund. The bag was $11.04 and it was the camo bag.
