Please answer this. Do you and your brother acknowledge the rules of the group buy that you agreed to. No refund can be given after the unit has been sent for processing?
Please answer that directly before you continue.
Sure. Group buy orders are sent to processing are based on public list of participants. Curiousminer was not on that list. you have stated that everyone who is not on the public list will be refunded.
You have scammed my brother asking for payment proof and when you got it at 13.04.2014 you have successfully attempted to scam him not responding to his further communication.
This is fact. It is archived at screenshoots.
You should confess to this, refund him, remove feedback, say sorry to him and crawl back to your hideout full of evil.
