Hello how may I help you? Hi! I need help returning an item. What would you like to return? I just received a helmet and the chinstrap fell off when I picked it up. Sorry we can't accept returned goods here. But the person I talked to yesterday said there's a 30 day guarantee!!! They must've been mistaken My mailman is never mistaken. The mailmain has no knowledge of our return policy He's really smart. I can't use a helmet without a strap. It's like using a unicycle without a wheel. You know, i bet you're right!
