If you bought something online and Decathlon sent you the wrong size, it's easy to return it. Just follow these steps:
1. Go to "My Purchases" in your Decathlon account and click on "Start the Return Process." Choose the order that has the wrong item and click on the "Return Product" button. Write "wrong size received" as the reason for the return and make sure they understand your request.
2. Get the item ready to be returned by making sure it is brand new, in its original box, and with all of its tags still attached. Put it safely in a box that is made for sending things back.
3. Depending on where you live, you may be able to mail the item back or take it back to a Decathlon shop. If you want to return something online, just follow the steps given when you start the return process. If you'd rather return the item in person, take it to the Decathlon shop closest to you along with proof that you bought it.
Decathlon will send you the right size after they receive and process your return. Processing times can vary, so it's best to check your email for updates on the state of your exchange.
