If OKX imposed unexpected costs during your cryptocurrency swap, begin by analysing the transaction details in your OKX account's "Order History" or "Transaction History" section.
Compare the listed fees to OKX's official fee schedule on their Fees & Limits page (https://www.okx.com/en/fees.html) to check if the charges are consistent with usual rates.
If the fees appear to be inaccurate or unclear, take screenshots of the transaction summary, which includes the amount traded, fees charged, and timestamps.
Submit a support ticket via the OKX Help Center (https://www.okx.com/help) with all necessary information, including your account email, order ID, and screenshots.
To expedite the process, explicitly explain why you believe the charges are inappropriate and seek a thorough price breakdown.
Avoid creating multiple tickets to avoid processing delays, and check your email on a frequent basis for OKX's responses.
If you think you can propose better solutions to the question presented, we encourage you to offer your opinions or submit your complaints free of charge.
