We can request that an exception be made in this case but that’s not our call to make and my guess is that they would be unlikely to agree. Any operation with a 5 player minumum is not going to be keen an setting precedents.
In real terms, I think the quickest way to get this money released is to get collaboration between you and the Bet365 affiliate team and see how we can help drive those last 4 referrals.
We’ll do what ever we can to assist you.
