WSB is not a good betting platform

Specifically WSB and their relationship with EFC. First problem was when they notified me on the day of the actual fight card (on the exact time of the start of EFC 86) and they tell me some of my bets are void because some guys are not fighting and they have the incorrect athletes listed. It's not their fault because EFC notified them late. Then they match your deposit which is good and well but when I wish to withdraw, my actual winnings also get withheld. Not user friendly at all and take forever to process the winnings. Basically they make it as hard as possible to work alongside them.
