ok so you are a scammer
good luck with your sales.
i can see your last group buy had no interest, why?
becouse you are not mature seller.
you cant admit that you have made an error. you cant say sorry.
truth is my brother requested refund, you asked for payment proof, you got it and after that you have been ignoring him (since march till july)
you should say sorry but your devices cant be refunded (you have stated before that all people not on the group buy list will be refunded), please provide me shipping address. he would provide it.
instead you just have started your scammer silence mode, no answers to emails, pms.
this case will not finish like you would like. this proved scam will be attached to your nick forever. deal with it.
