Issues with the Riot merch Store.

So basically i'm having an issue with an item i received and also with the riot merch website. So in a nutshell; My mother ordered a hoodie (Gnar/Mega Gnar Hoodie-Medium) for my bday from the riot merch store in which we received in perfect condition but the item does not fit and we would like to send it back for the next size up. However my mother didn't sign in with an account and it seems without it we don't have any options in which to send it back, we even tried filling in our order number and my mothers email address in which she did receive 3 emails confirming the order. If anyone knows how we can send it back to either get our money back/request for the next size up that would be highly appreciated.
