Hello how may I help you? Hello, I recieved a defective product from your store. I'm very sorry for this. What would you like to do? We will have to return it I guess. Sure thing. You would need to call a customer service representative in order to make a return. What is the number? 555-555-5555. Is there anything else you would like to know? Could you send a new one while I wait? You would need to talk to the customer service representative about exchanges with this issue. For a bicycle helmet? Yes. It is out of my control as the customer service representative takes care of all returns and issues with products. Would you like any further assistance?
