As I sent them an email from the other account 2 days later and they allowed me to play but they didn't allow me to withdraw - so it was a trap.
They knew all the time I had two accounts so explain me why aren't they negligible for closing only one of the accounts?
It would be important for them to take this case and fix their procedures because they didn't make everything they could have done < it is needed to protect gambling addicted players.
You have asked to close the account to their representative, right? If yes, then have you told that representative that you have two accounts and you want to close/lock both accounts? If yes then it is the fault of the representative. But if you told only for a single account and later another account gets blocked/locked/banned by the automated process then you have the responsibility instead of the support/representative.
