Refund

i wanna deposit to buy mtx , but i wonder that can i refund to take the point back to buy another mtx when i bored with old mtx ?

I would assume you're asking to be able to change store cosmetics when you're bored of the one you purchased. I dont see that to make sense as people would want a refund on costumes when something new and cooler comes out.

My best suggestion is to buy one of the supporter packs that you like because they come with a portal wep effect ect and some coins you can use to buy specific wanted cash shop mtx.

also you can earn free mtx by doing league achievement challanges so there are ways to get free mtx and you want to buy stash space .

Any MTX refund is solely at the discretion of GGG and would be a courtesy.

So when you say "can i refund it when i get bored with it", i would say that isn't likely.
