How to show that Shenzhen Shenzhou Tongfu Co., Ltd. uses CCB online banking to pay the phone bill?

The page you pay for is just an interface. For example, you pay the phone bill through the bank website, WeChat, QQ, JD.COM and other websites, which only provide one interface. Third-party companies provide services in the background, such as Shenzhen Shenzhou Tongfu Co., Ltd. you mentioned. As long as you recharge on the regular website, there is no problem.
