I sent 1 ETH from my Rinkeby to Poloniex account on 18 Dec. It is withdrawn from Rinkeby on 18th itself, but still not shown in Deposits of Poloniex account (as on 9 Jan). I am able to see that ETH in Etherscan account checker. I have raised a ticket with Poloniex Support but they have not responded still. Please help me retrieve by ETH. The transaction hash is 0xcadd372f2b280b37dcd6328bf1f4160770858da7da0fd7addfa8c8086e084bdb.
P.S.: I see that other similar questions have been closed as being off-topic, if mine is also that case please guide me another forum to post this. Also I wanted to understand if this transaction from Rinkeby is any different from other questions.
Your help is much appreciated!!
