Dear User, We have reviewed the details of your transaction and the information provided by the exchange service. Please be aware that tokens on the same network can have identical names (e.g., USDT) but originate from different smart contracts. Our verification of the transaction hash on BscScan confirmed that the funds sent originated from a smart contract address flagged as suspicious/spam, and the transfer involved a "fake" token with no market value. Exchange services can only process or refund valid assets that match the expected official contract address. Since the tokens sent are not supported by the system and hold no value, the service is unable to complete the exchange or initiate a refund. We strongly recommend always verifying the smart contract address of a token before sending any funds. Since the issue stems from the nature of the assets sent, we consider the service's explanation to be technically justified. Sincerely, administration of the BestChange exchanger monitor.
