Complaint about a recently purchased iPad

Hi dear Apple team I recently bought Ipad Air with pencil pro together for 778€ as a student. But just recently I got information that apple is making discounts for students and my friend bought the same Ipad as mine for 639€ of course together with pencil pro. So the problem is I'm not seeing the fareness here because it's been only 2 months and the price is dropping with big deal and I'm loosing 139€. It's not fare especially for the student like me. So ask for price adjustment and ask you guys to refund the money that I lost which is 139€ I guess you understood my situation and hearing you back soon
