Any proof
photos of your wrong delivered miners?
Otherwise your are just trying to ruin my name
That means, you don't even have proper record of what you sent me.
Now I am REALLY worried.
I sent you 2 payments. 1 for $820 and a second for $220.
I have 3 of your $50 machines (not even worth the electricity).
Just send me back the balance, I don't even want to deal with it. I will just keep them as a vivid reminded.
