Hollywoodbets is a *******

I've placed a bet on Hollywoodbets 22 September 2020 on their livegames betgames speedy7, the bet won and they did not pay my winnings, I tried to contact them on their social media platforms they don't reply to my messages, I then went on to email them and I don't get a valid respond back, I'm fed up with Hollywoodbets their service, they are a total ****.
