Most products do not include after-sales support. A small number include support for 24 hours after delivery. Confirm eligibility, scope, and required information with customer service before buying; the specific product description applies.
Test a small quantity first. Products are not refundable or exchangeable once sold. For any after-sales request, use the real email address from your order and join the official Telegram group to verify contact details. Without both, the site will not handle the request.
Anyone claiming to be customer service and privately requesting payment is a scammer. Read the full purchase notice.
