I’m curious about this case, why does only your casino make this match considered firmly as fixed match while other casino doesn’t make an annual like your for the same match. Can you provide proof that other casino marked this same match as highly suspicious as per your opening statement?
It's pretty damn obvious that almost all casinos would find these bets suspicious to be honest which is why proof isn't really required here. Betting on lower level leagues reduces your account health drastically in any sport.
Fairlay clearly pointed out the links in an organised manner which is why op is an a tough situation regardless of whether he was aware of the fixed matches or not. His chances of recovering his money are pretty slim in my opinion.
