Why my education discount has been cancel?

I am a student in Peking University and have been studied in school of software engineering and micro electronic since 2017, will got my master degree in 2020. I have no idea why my education discount has been canceled.

If thats because my ip address imply i am in sinapore ,thats because i am using vpn for better connection.

I have tried to contact your team by GitHub Support, but nobody answers.

@AlgoHunt Try reapply again, it happened to me once for no reason and I just reapplied and it worked.
