Hi EdenHazard,
I' m sorry about your balance getting removed in CoinRoyale. As Ash and others have mentioned, according to our TOS, the funds in the dormant accounts are subject to removal, especially if the account is more than 5 years old. In addition, the email asking for the funds doesn't match the email of the accounts, which we definitely can't do it. We have emails coming in almost every week 'claiming' he/she owned the 'accounts' and asked us to send funds out to the address he/she provided. It's a textbook tactics by scammers and our team are very aware of it.
That being said, I'm giving you the benefit of the doubt for now as you're longstanding member here and a long time customer with us (I also remember talking to you back in the days). I'll PM you and work with you personally on further verification for your account.
This is the best gesture from the admin of the site to its users since as per policy it is fair what you stated and did it. But knowing the other side too and ready to be making changes if need be is the best thing because this is how you build the trust among users and also help in building a good reputation in long term.
