When I first submitted my withdrawal application, Nanya customer service said, "The system detected a discrepancy between your account's identity data and transaction data. You'll need to pay a deposit for verification. Once verification is passed, the deposit and principal will be credited to your account." They also sent me a "Data Discrepancy Report" stating, "Verification pass rate 65%, deposit required to increase to 95%." They threatened, "If you don't pay the deposit within three days, your account will be frozen and your principal will be deducted!" I transferred 30,000 yuan, but after a week, the verification was still "pending review." I contacted customer service, and they said, "Your data verification involves cross-border verification, and you'll have to pay an additional 20,000 yuan expedited fee." I asked for a refund, but they bluntly said, "The deposit has been used for the data verification process and is non-refundable."
