beastlymac why you have been ignoring my brother within 4 months?
until i joined to help him?

you have tried to scam him and you did.

rules for group buy are easy, people pay, order goods, you ship them.
if any data is missing to fulfill/refund order you should ask for them (immidiatelly when goods are ready to ship)

you just asked for signed message, and you have not paid 1 btc refund after receiving it. scam.

you have not done it. you just asked for payment confirmation, when you got it you went into silence mode trying to scam newbie.

you should answer: sorry no refunds your goods are ordered, but you are not on public list becouse shipping address is missing.

this is fact. this is scam.

please pay for your errors.
