If WeChat is blacked out and deleted by the other party after the transfer, you can immediately contact WeChat customer service and provide evidence such as transfer records for help. If WeChat customer service can't solve it, you can try to contact the other party through other channels to explain the situation. If all the above methods are ineffective, you can complain to WeChat about this behavior to protect your rights and interests. If the amount involved is large, you can consider calling the police. In short, keep calm, collect as much evidence as possible, and contact WeChat customer service to get an effective solution.
