Referees refusing to change score

[Lone Wolf]

I don't know if this has ever occurred to other teams before but I was wondering why there isn't a rule that allows referees to change scores for matches that are clearly scored incorrectly. During Q51 of the Glacier Peak District Match, the refs failed to count 20 points for assist and truss points (we still would have lost by around 10 points, but we needed those assist points). I stood in the question box a total of four times to talk with the head ref about score changes. I had video of the match (which unfortunately refs aren't allowed to view), asked to speak to other refs to see if I could trigger their memory, brought along a member of our alliance to challenge the score, and even got a driver of an opposing alliance for that match to help up ask for a replay of the match. All of this was rejected by the head ref. This situation was extremely frustrating for me, my team, and my alliance. Could someone explain to me why this happened and how to deal with this in the future? Thanks!
