other than telling you to show evidence that backs up your claims, I am not sure what more you need to prove your innocence. as I said before even if you provide evidence there is still no guarantee that they'll reverse they're decision.
Since you seem to know these things, I was just asking for advice. Because, as you say, I am not sure what I need to prove my innocence.
In lots of cases, innocence cannot be proven... That's why it's on the accuser to prove guilt instead!
How can I prove that I only have one account?
I already sent Stake all the "evidence" I could think of. I sent them my ID, income statement, proof of address, screenshots, selfies, transactions reports. I don't know what other evidence I can provide. And I am getting quite desperate. If they just ask me for something I could cooperate. Instead I have no clear information and I am left guessing and sending email which only go unanswered.
They just said "you're guilty, we'll take your money". It's unbelievable.
