Can you please write in more detail in the correct format? It's hard to understand what does happened there. If I am not wrong Etherflyer is a decentralized cryptocurrency exchange. They don't hold any assets themselves. So how they are not giving your withdrawal? I am not using any DEX, it would be a stupid question. But let's see the Definition,

 There is no legal organization you can make a complaint except the police. It would be easier to answer you if share more info with the domain name. Who knows if you are using the correct website or phishing site.

etherflyer dex değil mi yav? o paraya erişmeleri mumkun değilki.
hocam arkadaşın acaba etherflyer yerine baska phishing tarzı bir siteye girmiş olabilir mi?

bu arada agustos ayında gerekleşmiş transfer.umidi kessin arkadaşınız mumkun değil o etherin geri donmesi.

At first you should follow these steps to make a perfect scam accusation : Scam Report Format (Use it to make scam reports properly)  Also provide some proofs.

BTW are you talking about https://etherflyer.com/ ? If yes then I see there is a official ann thread of this project in this forum. And maybe this is their main profile here but the user is enactive now. etherflyerofficial

Merkeziyetsiz kelimesini ilgi çekmek için kullanıp aslında merkezi olan borsalarda bu tip kayıpların yaşanması normal. Gönderim işlemi hiç gerçekleştirilmemiş. Başkalarının cüzdanına bir şekilde aktarım gerçekleştiriyorsanız yani kriptolarınızın kontrolünü kaybediyorsanız o borsa merkezi bir borsadır. Biraz bekledikten sonra Scam Accusations bölümünde gerekli şablonu kullanarak bir başlık oluşturabilirsiniz.

Daha önce forumda açtıkları bir başlık var ancak yaklaşık 1 senedir hiç giriş gerçekleştirmemişler.

gördüğüm kadarı ile gönderme işlemi başlamamış bile herhangi bir gönderme işlemi başlamış olsaydı txid orada yazıyor olurdu belki işlemleri sırayla ve elle yapıyorlardır.

Bu gibi durumların önüne geçebilmek adına daha çok bilinen borsalarda işlem yapın. forumun globalinde konuya yazarsanız belki yardımcı olanlar çıkabilir.

It doesn't matter how many times you ran into problems using Yobit, the result is still that they pulled off a shady cheat. If there are no records of anything, and the funds vanished, it's safe to say that Yobit either purposely wiped out your balance, or there is a bug on their end being responsible for this.

Another possibility is that you invested in an altcoin and Yobit delisted it without you knowing, which usually means that it wipes out everything related to that specific altcoin and there is no way to get it back.

Hello friends
I invested 0.9995 btc on 28.11.2018.
but suddenly the bitcoins in my wallet disappeared.
In my past address there is no investox or yobicode
they do not respond to customer service.
How do I solve my problem?

Seems you have been waiting for a long time, haven't you tried to contact Yobit on this forum? This is their profile link and last time they were active was 28 February: https://bitcointalk.org/index.php?action=profile;u=406594
You could try opening accusation thread here but they rarely login on bitcointalk, well, try to PM him. Also still tey and send emails, at least if nothing, you tried your best.
But please don't you know that exchange that lists dead coins won't be good? Nothing to talk about some research around it.

Yobit is probably the shadiest exchange operating right now.
