I was recently playing with a friend on an online casino sight. The game was lightening roulette. On the same account, two days earlier we had hit 500x on a number totally to £30,000. I had requested that to be cashed out and was feeling lucky again so played. I hit another 500x number and the total was £32,000. I logged out with the total balance remaining on £30,000. However the next morning I get a call, telling me they would be clearing my balance back to 0 and I wouldn’t be getting paid a penny from the second win. The reason being whilst playing because some bets were being rejected, I had a team member pop up on the live chat suggesting me to stop playing. I don’t know how to approach this, 30k being a massive sum of money for it to be swiped from under my feet... any suggestions?
