Verb required with discount (formal writing)

Hi

Could you please tell me a suitable verb? Is the rest of the sentence OK?

(Job Offer Letter--teachers are offered a special discount on their children's tuition fee in the school; if they leave the job, they are no longer entitled to the discount.)

However, if you decide to leave the job, the discount offered on your child(ren)'s tuition fee will be ________________ from the following month.

Thanks,

Tom
