Tournament rank display discrepancy

This is really starting to piss me off. I won a match that actually told me I made 1002 points in the win screen for the venom tournament. By the time I go out to claim my reward, I'm informed that I've been attacked and I'm down to 979 points. What then unfolded was an indescribable kicking of my **** that dropped me to 850 rank points. I feel pretty robbed at this point.

If I'm told I have enough points, I should get the damn progression prize. Fix your ****.
