I think you need to follow up again to Kraken if you're issues has persisted. I don't know what is happening and totally deducting to your funds. I guess you are not alone having issues with them so the better way is to really making follow ups to see what is going on with your account. I don't know if this is a software bug or something because I know there is also a reddit members that complain a similar incident as yours and Kraken was quick to answer it and says it has something to do with a flaw in their software or something or they can't reproduce the issue which is really funny to me. Just continue to bug them mate.
