Will you give the ownership of your account back to Bayuo if you get a refund from Quickseller? Also, if he agrees to give you a refund, I would advice you to go through an escrow to make it publicly visible that everything's going under a genuine way...
If I get a refund, it will be in Quickseller's possession. It will be up to him. And I will definitely use escrow.
I am not sure why you are trying to label me as such a scammer. If I was going to scam you then I would not have given you anything after you sent me 1.1
BTC for your account without escrow (assuming you are the same person that purchased the account from me).
You appear to be making good on your threat on trying to ruin my business if I did not pay you 1.1
BTC that you are not due.
