What should I do if I save my phone bill but don't refund it?

General telephone charges cannot be returned in time under the following circumstances:

1. When participating in contract activities, it is required to use calling cards in combination, but the calling cards are used separately. If the contract is not fulfilled, the phone bill will not be refunded.

2. After the loss of the mobile phone is reported or stopped, it will affect the return of the grant.

3. If your mobile phone is lost or damaged, take it to the maintenance point for repair, separate the calling card, fail to match it in time, and fail to untie the calling card in the local business hall, the phone bill will not be refunded.
