When I first submitted my withdrawal request, the Vietnamese customer service representative told me, "Your funds need to be transferred back from an overseas server. Cross-border data transfer requires a dedicated channel. After paying the channel fee, your funds will be credited to your account within 24 hours." They also sent me a screenshot of a failed data transfer review, labeled "Channel permissions not activated," and threatened me, "If you don't pay within five days, your data will be frozen and you won't be able to withdraw your principal!" After waiting three days, the withdrawal status was still "under review." I contacted customer service, and they said, "The channel traffic is insufficient, and I need to pay another 20,000 to upgrade the channel level." That's when I realized it was a scam! I asked for a refund of the channel fee, but they bluntly said, "The fee has been used to activate channel permissions and is non-refundable."
