Recently requested a character restoration after accidentally deleting the wrong character as I was prepping for world transfer. As soon as I realized what I did I went straight to the Support Center and submitted my request. It'll be possible to restore my only problem is I've gotta wait 24 hours to be able to submit my request and it actually be restored. I'm assuming it's server side. Other than that response was quick and the customer support I spoke too were also very friendly. Just wish I didn't have to wait so long to even submit a request.
