****** on online games

So I have been using Hollywood bets since they have been online and operational. Mainly for horse racing bets. When I have free time I play the revolution casino games. My bets are always rejected especially when winning. What has made me turn to hello peter today is that while playing a casino game called mega ball I placed a R50 bet which displayed on my cell a bet taken for R50 a few seconds later when nothing drawn or any appearance on my screen I see my bet displayed at R450 which I clearly did not place. I have been using this site and games for a while so I clearly know how to play and amount my bets. I have numerously contacted the live chat on the casino games and have no luck and always given a response they working on it. I am sure Hollywoodbets can view my bets taken and the client I am and if this is not resolved I will cancel my account and use another betting site and will pass the message on to all my fellow horse racing mates who also complain about the odds of the horses and website giving issues. We are a group of 150 people on watsapp who use this site and I'm sure you wouldn't want to loose 150 big punters. Kindly review
