Can you explain how the problem was solved, the topic will be good for those who face such problems in the future?
I thought that you had opened the wrong balance (the wallet has several balances, and you can get a smaller amount if you change the wallet settings to show one of the balances and not their total.
Next time, avoid using this platform or buying currencies from them, the fees are high, the privacy is low and the possibility of losing the balance is high.
