Recently I have registered to Royal Vegas casino. On my very first deposit I was offered a few deposit bonuses, I chose to deposit without bonus, but a bonus was still added to my account. I have contacted support to remove the bonus and they did that. On my second deposit unwanted bonus was added again. After contacting support they removed the bonus. Also I have asked to stop giving any bonuses to my account in the future. They accepted that so the agreement was made (no more bonuses at all). Few days later I was playing at live casino and lost a little bit. While still playing at the table I made a deposit and kept playing. Next day while reviewing my statement I've mentioned that there is a bonus of 242.50 EUR in my account again. After contacting support they refused to cancel bonus because bets were made when bonus was added. Bonus wasn't received instantly after deposit. It is not clear when it was dropped to account. Looks like, they add bonuses whenever they want. And that is how they suspend all your money.
Long story short:
Casino agrees to not add any bonuses to account, ignores it and still adds bonus in the middle of playing without any warnings or messages (so you can't see bonus was added), then refuses to cancel bonus because bets were made after that. And even refuses to let you withdraw your initial deposit.
