Did the problem not yet to be resolved still? maybe you can please share your ETH address and BTC address so that people can take a look into it.
If you accidentally send your OMG token to your ETH address and blockchain.info didn't recognise, big chance they didn't support ERC20 token and so on.

or if you accidentally send it to your bitcoin address, well, it's impossible to be done since the address of ETH and BTC is really different. Don't know if this topic in the right section tho, supposed to be moved to altcoin section.
