Vodacom shop bushbuckridge

Vodacom shop bushbuckridge twin city i bought Samsung S24 December 2023 As a payjoy customer so the phone was handed to me after purchase however I was never warned about S24 camera to be faulty as they have had customer come back to complain too .so just a few days as i try to capture a beautiful moment on the 15th which was a very important day i couldn't so i thought maybe I should take it back to be checked and when I did the guy who could attend to it was not in so i had to go back and come back another day. And I did so on the 8th of Jan 2024 I was told it needed to be taken in for repairs and I agreed and they didn't log on their system that it was on a payjoy account and I had paid weeks in advance so by the time it was returned it will still be ok and won't be on arrears but i had done that nor because it was going for repairs i had paid so i can finish the contract fast.but now im stuck with a phone that has a none working camera that i need because I bought it for the use because my work requires a camera.now nobody wants to either give me a new working phone im told i need to pay arrears on my payjoy to be sent back for the 3rd time in 2 months thay I had left the phone with them .I then decided to take it hoping Vodacom shop will hear my complain and give me a new phone so i can continue paying my pay joy account and please help if not someone needs to give me answers why sell me a faulty Samsung S24
