I didn't claim the welcome bonus on the new account.
What is it that you claim and on which account? Your statements are confusing me. You did not claim welcome bonus on new account, but on the same account you claimed free spins? Though, I told you already that it does not matter if you claimed it or not, if you have withdrawn anything from your old account that was out of a bonus, then you will face problems ahead.
Haha welcome bonus is a deposit bonus 100% of the total deposit while 25 free spins is an added bonus without the need to make any deposit
The difference of 2 years between the old account and the new account is not really a reason to cheat the casino that's normal because we might forget the old account
