What a dissapointment

I dropped off my car after it has been approved by my insurance, I then went away for 3 weeks. Assuming my car will be ready or almost ready by the time i get back. While i was away my car was seen driving on the roads without my permission. According to the website tracking process of Renew-it, my car was going through final inspection and it wouldn't take much longer, a notice said "speed bump" with regards to parts not arriving. How on earth did my car make it all the way to final inspection if parts had not arrived.
