They are some seriously bad books to be rated so highly. Uncompetitive odds and slow to pay.
You need to be betting with books that offer better odds and pay quickly.
I'll recommend the following.
Bet365 - best odds, high limits and fast payouts.
BetSafe - Competetive for best live betting and good odds, quick pay outs.
VictorChandler - He's a player, will take you on, pays fast.
TomWaterhouse - He knows what you want.
All those books have HIGH LIMITS, some of the best odds and pay quickly.
