If you sent a deposit of a currency not supported by Amplify Exchange's wallet, then we have not received this deposit, and as such have no access to the deposit nor ability to recover the deposit. This may have caused the deposit to be rejected, and thus returned to the originating entity that sent the deposit. Please review your transaction history with your depositing company to determine if this occurred. If someone else received the deposit, we recommend you contact the owner of the address and resolve the misdirected deposit with them directly.
We make no guarantees on recovering deposits, as per the Account Funding; Transactions section of our Terms and Conditions:
"We are not able to reverse any transactions and will not have any responsibility or liability if you have instructed us to facilitate sending Digital Currencies to an address that is incorrect, improperly formatted, erroneous or intended for a different type of Digital Currency. We are not able to reverse any transactions and will not have any responsibility or liability if you have submitted instructions to send fiat currency to an External Account that is incorrect, improperly formatted or erroneous."
