AliExpress does not have a customer service to contact. If you did not receive your order you can not get refund from seller. I ordered from seller "Shop1103778248 Store" they charged me $145 for an order that I did not receive it. They just send a message "delivered your order look around, ask your neighbor to find it - No Refund". They don't mind you received it or not. AliExpress did not protect a buyer, so I think Scam or bad sellers can use this website to sale and collect money from buyer. If you buy from this website, don't buy this seller "Shop1103778248 Store"
