    Sapo — Sapo cực kỳ lưu manh Ép khách mua thêm ứng dụng chứ không đồng ý cho kết nối vào trong khi dịch vụ Sapo không hỗ trợ cái cơ bản nhất là hỗ trợ thanh toán trả góp bằng cách check ngay nút mua hàng. Mọi Người nghiên cứu kỹ trước khi ký kết với Sapo nên tham khảo các bên dịch vụ web uy tín khác.
