Rules are important, and this is why we have them.
"6. Teams consist of 5 members, and 2-3 substitutes. If team fails to bring the requirements, they will play as is or forfeit."
Alexander agreed to the time, and therefore committed his team. The 5th team failed to bring the required amount of people, and as the rule says, they may play as is, but according to the VV and ref, the VV offered to play 4v4, which the 5th denied. Therefore, the 5th team has no option but to forfeit, and take the 8-0 loss to the VV.
Decision is final.
