First of all, I would like to suggest you to properly blur the email address in the screenshots (I am telling you incase you did not notice it).
1win is having a good reputation here in the forum and also run a signature campaign here. $8000 is a lot of money. Have they returned your deposit of $5000 ? I know you cant access your account so if you can provide more details about your betting pattern on the site, it might help your case to gain some attention.
My deposit wasn’t returned. I registered in 1win on October 10th and have placed there few hundreds bets. In attachment confirmation of registration. Regards

Before you lock this thread, please add more information beyond the registration thread, as this is not enough. Drop all available emails that you received from 1WIN I have tagged @Mate2237 to help you. In your case, you can send him details of all your proofs, including transaction details, if it's possible.
You need to accept that the decision is final and hope your deposit will be returned; this should be at 1win's discretion.
