Broken goods

I bought light trims for my Amarok that i had to pay more than R500 included courier costs. When it arrived i opened the box and saw the trimmings inside wrapped in plastic. I stored it from 14 August 2021 up to 20 October, waiting to recieve back my Amarok from my mechanic. When i took out the trimming i saw that its broken in 2 places when i took it out from the plastic. So i contacted them with my problem and they flatly refuse to replace the one broken trim due to there terms. Offered me a new one for R200 and a reduced courier fee of R50. So if you order anything from them, make tripple sure its in a 100% condition, they wont assist you after 7 days.
