Hopefully you get a reply soon but I wouldn't open a second account as this is asking for trouble. Most probably, when you try to withdraw you will get flagged because you have 2 accounts and loose your winnings. The only way it would be allowed if you have confirmation from the Roobet team that it is allowed.
@seleme don’t do it opening a second account is not a solution, but an invitation for future hassles because even if you’ll be able to deposit you won’t be able to withdraw your winnings and deposits so don’t do it. I would strongly recommend wait patiently for the support to reply, but doing what you suggested is madness and if you do it then you’ll regret your actions in the future.
