Okay, but what would that refund entail?

Pause the subscription where it is, and let you come back without time changing on your subscription left?
Refund endwalker?
Refund the entire game?
Pay you for your subscription time left?

What would you do to get that refund? Delete your character and never play again? Or are you going to come back in a month, and all you really need is a way to really pause your subsciption so you don't lose any of what you paid for until then?
