PokerStars Support
The PokerStars support desk is often singled out as one of the best in the industry. They are generally regarded as one of the most efficient online poker help-desks around. If you're online, there are always members of staff waiting in the chat to field any questions. They are often the first point of call for troubled players and are also on hand to help carve up prize money during MTT final table deals.
You can email their support for just about anything, such as requesting your past 500 tournament results or asking to investigate a player for cheating. They take collusion and multi-accounting very seriously and will research the play of players. The PokerStars support is the best I’ve ever dealt with.
