Coin Mining HQ — mining electrical unit
I paid about 6000 for innosilicon d9 (a mining unit for mine crypto currency) but they just sent me a very cheap electrical board. After that they never answer my emails at all. of course they don't have any phone number and any physical address. They have just an email address for cantact to their customers. But I just know they send me the mistake order from an office in Hong Kong. Is it possible to find their address through the post office?
