why u not print the order confirmation details sent by bitmain to your email (when u paid for the order); and show it to DHL..
it is basically an invoice? is in it?
They do not accept something like that.
Even it was a CC payment yeah that would work but it's a BTC payment. Btw they have sent me an email that your order is being cleared now, I did not understand how this happened. Maybe they did something from China DHL?
Tomorrow things will be more clear. We'll see.
