Employer Trying To Mess With Unemployment

I recently got “terminated” from my job (California so at will state) and my employer is lying to the EDD office. They are chronic firers and fired 4 people in the last year(only 12 people work there). The person in my position previously was fired in 2 months, but then they restructured due to how slow we were and my position got eliminated. When they told me I was getting terminated they didn’t cite a specific reason just told me they wish me well, but when EDD called them they claimed I was fired for misconduct (not clocking out for lunch). Our time system had a problem with registering clocking out that I’d emailed them several times about, but because EDD thinks I lied about my cause for termination I’m not eligible for unemployment. I’d never been written up or given a PIP. I think that they want to contest my unemployment because they fire so many people their unemployment insurance is through the roof. What can I do here?
