no don't unjailbreak your device, just remove the app/tweak from cydia and make sure it was turned off from the setting menu first. then contact apple, tell them nothing about your device being jailbroken or that you know why the transaction didn't go thru (This will void the refund!) and just simple tell them you did not recieve what you paid for they will check themselves and see an error has happened ghosting the transaction and will credit your itunes account again
