Attention:
This OP is a real scammer and his name on Telegram is JAVA SSM (maybe he has changed already)
He used dirty words all the time, he planned to PUA and drive us crazy, then we may send BTC to his "new" wallet address.
Luckily we have a safe payment and refund process, our finance colleagues are very professional so we need to submit for approval with receipts. What's more, we have technician colleagues who are very professional too, they helped us verify both Email addresses, and this scammer is using a fake email system, that's why he could send us Emails with our real customer's Email address.
BTW, here comes proof from our customer (Agreed by our customer)
