Hello how may I help you? I got a defective bike helmet from Dicks Sporting goods last week and I want to return it. I can help with that. Do you have your receipt? I do. I have it in my email from the store. I have located your purchase. Returns are simple. You can return the item to your local store, or you can return it through the mail. Which would you prefer? I would like to return it through the mail. How should I go about doing that? I have authorized the return on your item and have emailed you a return shipping label. Please see your email and make sure you have received it. OK great. I just received the email! Excellent. Now simply return the item to its original packaging, apply your label and drop the package off at any post office. Ok thank you for your help. Is there any specific date I have to have it mailed by? The label is good for 30 days. your refund has been credited to your account.
