I opened an account on Roobet site few days ago, I have some money that I won in bets, they are still there. I don't remember which email I created the account with. Now I will login to my account.
It's quite strange that you forgot the email you used when registering even though it was just done a few days ago, maybe you can use the forgot password feature and enter every email you have because if you enter an email that is not registered there will be a notification that the email is not registered or you can use the method from Apocollapse, and hopefully you can again have access to your roobet account.
