COCA Wallet accepted my USDT deposit but I cannot withdraw it. Support is not responding. Has anyone solved this?

**Warning about my experience with COCA Wallet.**
I made a **test transfer** of **20 USDT on TON** from Bybit before trusting the wallet with larger amounts.
The transfer was successful and is confirmed on the blockchain. The balance is visible in both COCA Wallet and TONSCAN.
However:
I cannot swap USDT to USD or any other cryptocurrency inside the app.
The app says USDT swap is not supported.
I cannot withdraw my own USDT because COCA requires an additional deposit of **0.2 TON**, which was never disclosed before I deposited my funds.
Support has not responded.
If this limitation exists, users should be warned **before** they deposit funds, not after.
I am asking COCA to explain how I can access my own funds or resolve this issue. I’m really confused with that situation because it’s the first time when I can top up the asset, but can’t do anything with that money. Does anyone solve this problem with Coca? Actually I don’t want use is service any more but I want my 20 bucks back )
