If you received a different item from the one you ordered, the best thing to do is contact the marketplace where you purchased the item to request a free exchange for the correct product.
In some cases the marketplace may just issue a refund instead of processing an exchange order.
Whether a free exchange order is processed, or a refund is issued and you place a new order, please just be sure to update your order number for the associated redemption using the link below.
The customer service contact information for all marketplaces that Rebaid supports is listed below:
