Its not a fraud, that woman at Bitmain probably wasn't informed about MiningSweden and then the OP freaked out.
Its scammy though on MinningSweden side "We have now information about that the new S9 miner soon will come out on the market so now you can preorder your mining shares with the new S9 Miners."
So they don't tell a timeline ... just that your buying "2000 GH S9 Mining including all costs for 12 months." So they are selling these "shares" banking they will make money with no stat date "This product doesnt start mining before we have them in the farm". It's kinda scammy to say the least.
In the past they did that to the S7 and it wasn't a scam.
