Thank you, I will do a Scam Accusation.

I just want to say one more thing.

I had to tell him the exact amount I sent to the mixer adress otherwise he said he wont refund. I wrote him an email with transaction ID and told him the exact amount.
The next day he said he refunded (what he didn't).
With that the amount that was sent to the mixer adress is exactly proofed and clear, means, he confirmed this amount I sent to the mixer adress that I sent you in the proof in the PM.
I also can proof that the adress belongs to me.
The sender adress is also clear and there it can also be checked if any refund was received by the sender adress.
There you can see that nothing was received. No refunds.
