Multi-Service Operations

// Combine multiple services
EcommerceService ecommerce = wxPayService.getEcommerceService();
TransferService transfer = wxPayService.getTransferService();
ComplaintService complaint = wxPayService.getComplaintService();

// Orchestrate complex business flows
// 1. Process e-commerce transaction
// 2. Handle transfers
// 3. Manage any complaints
