I could not find any instructions for the Coin Bank wallet but, what you need to trace a transaction is the transaction ID. Once you have that there are various websites, you can look it up on, like http://blockchain.info
I would try contacting Coin Bank to find out how to get the transaction ID and try to deal with it as a lost transaction. The truth is, your BTC may be lost. If the transaction is not yet confirmed then there may be hope, you could try RBF (replace-by-fee) and instead send the BTC back to yourself or, you could try and double spend with a higher fee before the original transaction is confirmed. Both of these possibilities will depend on what features Coin Bank have available; it may be possible for them to do this on their backend if you cannot do it yourself in the wallet?
Also, Bitcoin and Ether are not compatible. I feel bad for you. You cannot send Bitcoin to Ether; it will not work. By the sound of it, Coin Bank may not have any send to address checking because the address you are sending to does not even look like a Bitcoin address.
