Account 1514881421@qq.com traded on the Sunergy Futures platform with a principal of around 8000U. It shorted when the news of oil price plummeted and made more than 150K U profit. The platform unilaterally refuses to withdraw, claiming that they have received "black U"! 1. Complete KYC verification, all information is true. The platform required to complete real-name authentication (KYC), my client submitted clear documents according to the regulations, and completed all certifications. 2. All account operations are done by the client himself, with no violation. 3. After making a profit, the platform refused to withdraw money on the grounds of "black U", and even asked my client to deposit another 5000U as a margin to verify the account. This is completely unreasonable - if they need 5000U, there's already 150K in the account, what does depositing another 5000U signify? Are they trying to scam again! 4. One-sided claims of receiving "black U", but there's no evidence of obtaining "black U", and even asking my client to find the source of "black U" himself. If the platform has determined that it is "black U", why don't they have evidence of the "black U", and ask my client to find out? All the reasons and excuses for refusing to withdraw are aimed to appropriate the profits. Their talked-about "black U" is a shield, essentially, they are bottomlessly infringing on the client's funds!
