BikeExchange is an online marketplace, meaning we help bike stores and customers connect online in one place. We are not an actual bike store ourselves, we support and promote bike stores around Australia on our site.
For help amending your mistake, immediately contact the store that you made the purchase with. Their details will be on the purchase invoice. Remember to quote your invoice number.
If you made your purchase whilst logged in to the website you can also find your invoice details in the purchase history of your account.
