TOYS R US

I bought a DIY Monogram water bottle for my daughter and its faulty the lid is on skew and all the glitter fell out as she opened it. The day i bought it my slip blew away as i go out off the store. So i took it back and the told me they need a slip to change it for another one as i explained what happens to the slip they said sorry they could not help me. Now i must sit with a faulty bottle my daughter are not happy as her sisters bottle are 100% and hers not. Why can Toys R Us sell faulty goods in the first place if you bought something you don't think it will be faulty. I phoned the customer care number and explained my situation and the said sorry they can not help. I am so disappointment will never again support TOYS R US again NEVER now my daughter are so sad and i must have something i have paid for but can not use it. What happened to TOYS R US they don't keep customers happy. Please people think before you buy something at TOYS R US the quality are not good as the sell faulty stuff and customers must be liable. Thats not fair. I'm very disappointed and angry
