I was by far not one of the last people to submit a refund request, but I am (apparently) one of the "handful" that have not yet received a payment of any kind. I don't understand why (maybe the promised repayment plan/process would clarify this).
Hang in there. I responded on 6/8. Did the Email and then just a PM to say see the Email. When he lost his Email account I think everything got reset. He seems to have sped up the repayments by a little, so hopefully you see you refund a little faster then promised.
