Engine repair crooks

The biggest crooks that you can find. Took my bakkie in for a new recin engine that only lasted 6 months. Took it back again for a leaking injector then we had to rebuild the whole motor again. This was in Feb 2022 only got it back in November 2022. I put in a new battery November 2021 and redid the alternator also novenber 2021. Jeep spares took my new battery and punt in a old battery. Had thebakkie for 6 days and had to repair the alternator again only to find out that it isn't the alternater that was repaired the last time. So i ask the question as to where is my alternator that was in the bakkie before it went in to jeepspares?
