They have already corrected the issue, at least for my transaction. Thank you for alleviating my concerns earlier. You hit the nail on the head and they have already initiated their wallet maintenance. My GOLF are now home to stay, Thanks again.
Coinexchange.io has now confirmed it has updated their wallet to the correct fork so it should be safe to transact coins to and from their exchange again.
I have received coins from the exchange that I transacted on the old fork so they have been processed on the new fork.
