What should I do if the 4s maintenance sends a text message to remind the coupon to expire?

For other discounts, please contact the 4S store.

1. Contact the 4S store: You can contact the 4S store on your own initiative, explain the situation and ask if you can extend the use period of the coupon.

2. Seek other discounts: 4S stores cannot extend the use period of coupons, and can seek other discounts or concessions.
