Citation was cleared by traffic school, but auto insurance still went up

(California) My auto insurance basically doubled, and my agent found the reason: a citation from October 2019. The thing is, this should've been cleared from my record by attending traffic school, which I finished early this year (months before the due date). I haven't had any citations since 2015, so this shouldn't stack with my previous one.

Called Fresno County court today and the rep said they sent my completion to the DMV months ago, so I'll need to contact the DMV for more info. However, I called the DMV and they refuse to investigate right now because it's not "COVID19 urgent".

My insurance premium is due next week. Do I have any options in getting this cleared and returning my premium to normal???
