Bet365’s “BONUS150” code finally worked after 3 attempts. Deposited £200, played 90% on roulette (their T&Cs allow 25% wagering contribution). Hit a £1.5k win BUT support said “system error” reversed it. Sent 22 emails, filed MGA complaint, got £500 refund as “goodwill.” Now banned from live chat. Worth it? Debating.
