So, I’ve just had my biggest ever online slot win. £3800 from a £20 deposit. I nearly died Haha. After I played a few spins at high stakes and left with £3400. When i cashed out it come up my account had been frozen. I have phoned William hill customer services who said when someone has a big win they do a game play check. Can someone please tell me is this normal and how long this takes to do?
TIA
