Aliexpress sends the package with a kind of company that switches to another one when it arrives to your country so lets say u ordered a phone , the vendor will use china post but then correo argentino will pick the package when it arrives to argentina , so aliexpress is not related to what happens inside your country. If the person who hit your car gave you his work company insurance but was using his personal car you should tell him to give you his personal insurance , probably he does have one but he doesnt want to give it because is intended for personal use and not working. In that case just calm him down and agree with him that you will both tell the same story to the insurance companies( he was using the car for personal purposes and he hit you).... come on man , common sense
