I Report UBS Investment Scam: My $12,476 Trapped in Atomic Wallet

I received a call from an individual claiming to be from UBS Yatırım (UBS Investment), asking if I had previously engaged in cryptocurrency transactions. When I confirmed I had, they stated their system detected a suspicious transaction on their network that might belong to me and assured me they'd investigate and call back. Five to ten minutes later, they called again, asserting that $12,476 belonged to me.

Following their instructions, I installed the Atomic Wallet application on my phone. They then directed me to transfer these funds, which they claimed were mine, into this new crypto account. However, this money has been stuck and cannot be transferred to my legitimate Paribu or BTCTURK accounts. The reason given is an absurd demand for a 0.22 ETH payment, equivalent to approximately ₺21,000, as a "transaction fee." Naturally, I refused to make this additional payment. As a result, the $12,476 remains inaccessible in the Atomic Wallet. This entire scheme feels like a sophisticated scam, causing me immense financial and emotional distress. I demand immediate release of my $12,476 without any additional fees.
