I played for about 70 hours in two months, and exactly couple of days after I reddemed a voucher, they decided to put my account on hold due to (obviously not) playing with a bot or vpn. Mailed them twice asking how to solve the situation. Never had an answer with the first ticket, and on the second time just redirect on the website to read the terms and conditions page after told that my account has been completely blocked. Useless to say that the voucher has been blocked and canceled.
