Query: cool backpack, poor quality

We got this backpack in Mid April. In Early June, the zipper on the side pocket broke off rendering that space now useless. We love the colors and it's a pretty good size for school and PC, but I'm really disappointed in the zipper coming off so easily with just regular use. If there was a way to get it replaced or repaired then the rating would go much higher.
