My question involves unemployment benefits for the state of: California

So I quit my job at Vans because my hours had been cut to the point where I had maybe 1 real shift and 1 call in which was just not worth it for someone my age (22) who has bills to pay.
When I filed for unemployment originally they approved of this reasoning and i got my benefits. Then Vans tried challenging this decision i had my checks stopped and another interview. EDD found me to be in the right and continued my checks. Now I got a letter from EDD office saying that Vans is now appealing the decision and I pretty much have to go to court.

I've never been in the situation and I'm not good in these situations. Will this be hard to win? What should I do? Will the Vans representative try hard to win or are they just trying to show that they tried to go to court like it saw on another document?

I hate this! Someone if you have any answers or useful information I'd be VERY appreciated.
