And at that point i could of ordered from another supplier but everywhere the prices now are over 10k$ which puts me in a dumb postion
You shouldn't really accuse some business that they are scam if they've managed to return your money. Some businesses never discloses reasons especially if they had a fault with their operations or in their business per se. Scam is a huge word and a hard accusation. Not defending them nor have any connections with them, but why choose them instead of those reliable miner sellers such as bitmain?
Certain reasons why this occurs:- they've never reached the quota of pre-orders
- they had an internal problem in their main business
- maybe their suppliers failed to comply to their agreement
And with that said, I guess this better fits on the Reputation board, as this doesn't really isn't a scam at all.
