Contact Ohmconnect. There is a soft cap at 2000 points to avoid overpaying (they had some issues previously of users with negative energy use getting overpaid). I've gone over 2000 before, and they adjusted it after I contacted them.
It happened to me once. When questioned About it, they fixed it. I was told was old restriction since lifted. I have had over 10000 points with a 2 hr mega. Yes = $100.00 for one 2hr event.
