Pizza Delivery Accident Insurance Law?

Hi, my car recently rolled in to a third parties garage that I was delivering to while I was on the clock causing roughly 750-1,100 dollars in damage. There was no injuries to anyone or any damage to my car except some scs. I made the mistake of filing a claim without any knowledge that I was not covered due to my work. I live in Pensacola, Florida with basic personal insurance. I've read a few places about case laws that actually make the clause in the insurance policy towards pizza delivery not be covered obsolete. My insurance company is going to deny the claim and drop me. Is there any case law like that for Florida? What can I do? I know about that Respodeat Superior law and that I can apply that to my employer. Please help.
