How did you get it back when you charged your friend 500 phone bills?

It can be recharged to a third party and returned by the counter staff. According to the query, China Mobile official website shows.

1. If you recharge through third-party platforms such as WeChat and Alipay, you can contact relevant customer service for consultation or apply for a refund.

2. If you are recharging at the front desk of the business hall, you can contact the window service personnel to apply for canceling the recharging operation.

3. All the above methods need to provide correct information such as mobile phone number and service password. If it is not available or uncertain, it is recommended to contact the local operator for customer service consultation.
