Bitexen Crypto Balance Disappeared Twice

I have been using a Bitexen account for many years and I had approximately $250 worth of crypto assets in my spot wallet. About 5–6 months ago, I realized for the first time that all of my assets had been deleted from my account. After I submitted a complaint on a consumer platform, my assets were returned to my Bitexen account and my balance appeared normally again. Because the issue seemed to be resolved, I did not log into my account for about 2–3 months. When I checked my Bitexen account again 2 days ago, I saw that all of my assets had been deleted for the second time and my balance was shown as zero. I also checked my Bitexen Global account and it also shows a zero balance. In other words, my assets that were previously visible and returned after my first complaint have now disappeared once again. After noticing this second incident, I called Bitexen by phone. I was told that my account had been transferred to Bitexen Global and that Bitexen Turkey could not do anything about this situation. I have been sending emails to Bitexen Global continuously, but I have not received any response so far. I have no screenshots of my old balance and the platform only allows me to view a 30‑day transaction history, so I cannot obtain older transaction records from within the system. Since the deposits and purchases were made about 5–6 years ago, it is also not realistically possible for me to access those very old bank receipts any more. I request that my account be thoroughly examined on both the Bitexen and Bitexen Global sides and that my approximately $250 worth of crypto assets, which disappeared twice and are now shown as zero, be restored to my account. I also expect a clear written explanation as to why my balance keeps disappearing and what measures will be taken to prevent this from happening again.
