gift refunding?

hey everyone, so since i was getting really good with my friend bought be the pulsefire skin on him as a surprise.i like it a lot, but i would've never have bought that skin and i feel like he wasted his money since i prefer TPA and debonair. so is there a way he could refund it because i've never even met him in real life and i feel bad that he spent 30$ n a stranger (we play often together but still...) if this is not possible, why doesnt riot make it happen? same thing happened with another friend i know in real life but he bought me gangster
