Hollywoodbets is basicaly *****ing from my winnings

Ive been gambling a long time but only recently discovered that ive been loosing thousands where i placed high bets hit great combinations and recieving 70 cents per win right after a big intro showing 200 and up then starts running down to 70 cents. This all happens so quick, its almost to difficult to spot so i had recorded one or 2 of my games where this has happened on a game called fruit shop megaways is where i picked it up first time.then when you log a complaint they rudely give you the wrong number twice and when you ask for a solution after loosing thousands because of this they just dont reply
