The 17 TRX deposit might not be credited to your balance but if the transaction went through and is recorded on the blockchain, MetaWin definitely got it. It reached their wallet. I would first get in touch with their support personnel and explain in detail what happened. Ask them to credit those 17 TRX to your account. Alternatively, see if it's possible for you to deposit the difference (23 TRX) and get a total of 40 TRX into your account. It's your mistake but surely fixable.
