Github Student Pack promo code can't be used
At the beginning, i want to use the Student Pack promo code, but the promo code typing blank cannot be edited.
I try to pay by paypal, but before i commit the bill, the promo code typing blacnk cannot be edited too.
So, i think i can pay in advance, and then maybe i can use the code.
However, it remind me that the promo code cannot be used.
What should i do? (i just paid now)
