Bumper

I bought a preowened car at Hyundai Weltevreden park not yet 2 months... 2 weeks later I booked it for brakes..then I hit a small pothole and the front bumper fell off on one side I called the sales man he told me I should tigh it to avoid father damage n so I did I then I booked it in for repairs because the was old glue n the bumper missed *****s but I was told it's the managers call to decide if they should fix it or not till today i am waiting and now my head lights are also falling off n when we check there's still a lot of *****s missing. I'm starting to think I was sold a car that was involved in a accident and not properly checked because even the back bumper is not properly aligned...
