Since all products are unique, we do not accept refunds or exchanges. We do not accept order cancellation requests or item returns unless the item you purchased is defective at the time of our confirmation. If you receive a wrong item, please contact us at 777mustars@gmail.com we do not accept refunds for defective or wrong items after 7 days of receiving it. Please email us first with your order number, product details, picture of the defective part, and your order invoice. We will contact you if the item is eligible for return. To be eligible for a return, your item must be unused and in the same condition as we sent it to you. It must also be in the original packaging. If an item cannot be replaced, the purchase price will be refunded.If the package tracking is marked as "Delivered," then technically our responsibility ended there. USPS has the coordinates or GPS to determine exactly where the package was delivered when it is scanned. The buyer can contact their local post office to get the GPS information and also ask them to check with family or home if the item may be lost. Or, they can submit a request for help with research online.
