I would suggest you submit another support ticket detailing what you have here, keep it succinct, factual and to the point expressing that you dropped the ball and let the resolution period expire and ask if there is any possibility of having your stats repaired. It's a long shot, they will not reopen the case but they may consider repairing your refund rate given the circumstances. Do not write them a novel, do not get emotive, just explain what happened and see what they have to say.
