If you are seeing a negative reward point balance then you were paid out extra the last time you redeemed points. Occasionally there is an error in the system that allows you to redeem more points than you had. We won't make you pay the extra money you received back to us, though you will see negative points until you have made up the difference.
We can verify when you received extra rewards and how much; just send us an email at support@tvg.com
