I participated in BetOnline's FIFA World Cup Challenge based on the rules and payout structure that were advertised when I entered. As the tournament progressed, the rules and payout requirements appeared to change, making it difficult to understand what prizes participants would actually receive. I feel the promotion lacked transparency and consistency. If a contest has published terms, those terms should remain in effect for existing participants or any changes should be clearly communicated and honored. My experience left me with little confidence in BetOnline's promotional contests and customer service.
