Hello and thanks for brigning this to our attention. We will look into it and if necessary take further action. We advise anyone to proceed with caution when it comes to (rather lucrative) offers of third party staking platforms and wallets. If it’s too good to be true, it usually is.
In order to delegate your stake you don’t need to send anyone anything! Keep this in mind.
