I have contacted Steve at the beginning of the week but no answer yet. The support told me that today:
"
Our team will double-check if your limits can be raised.
As per checking with our Sportsbook team, unfortunately your limits can't be raised right now.
"
Don't you get it? They won't reverse their decision since they know that you're a consistent winner which is something sportsbooks and casinos absolutely hate.
They reduce limits randomly for different winners based on various factors. These decisions make sense since they want to keep their business afloat even though it sucks for the winning gamblers.
Some sites like Pinnacle etc never reduce your limits. Betting exchanges also don't reduce limits since they don't care whether you win or lose.
