I just accidentally clicked on 'ok' to buying an item when I was viewing the cash shop items, but it isn't one that I actually wanted to buy, is there any way to reverse this? To give back the item and get my credits back? ( It's not a good idea to view items in the cash shop using a kindle ;w; )

i don't believe so because it was a user error. However, you can try trading/ selling the item for your sP / CSC back and then using that to buy the item you wanted to.

This is what it says on the CS page:

Thank you :)
