Hyundai after sale service putrid

I bought a car from Hyundai Brackenfell in December 2018 . The after sales service is the worst i ever experienced. My car was missing the boots backboard. Hyundai advises me that they have ordered the board and will deliver it to me within 2 weeks. I am still waiting for the boots backboard and is a terrible inconceivable. I can’t leave anything in my boot with it being visible. It’s been 6 months.
