Can anyone help me to get my money back?

I OPENED AN ACCOUNT AND TRANSFER TO MY MANAGER WITH 15,000EUR BUT NEVER USED THE MONEY. ON THE 7TH OF DECEMBER OF 2019 I REQUESTED THE WITHDRAWAL OF THE TOTAL AMOUNT BUT NEVER GOT MY MONEY BACK. THE ORDER IS STILL PROCESSING. I SENT SEVERAL EMAILS AND SPOKE TO SEVERAL AGENTS AND STILL DON'T HAVE AN EXPLANATION. MY ACCOUNT NUMBER IS 21032693.
