Hi I'm new here and I'm in a bit of a pickle I joined grand ivy and deposited which included the match bonus. I wagered my winnings 35 times and won £1600. I waited the 2 days to withdraw it but now they have denied it as ive breached their rules they are saying that i wasn't allowed to play more than £5 at a time on bonus rounds! I didn't know this and I feel I should have been told clearly. Where soon stand with this please if anyone knows.
