Unhappy customer

I bought a Xaomi Redmi Note 11 at Vodacom shop in Sandton on contract on the 28th of June 2022 as my phone had been ****** the night and I need a phone urgently because of my work. With less than 7 days with the phone in my possession when someone Video called me on whatsapp I realised that the front camera doesn't work even after I had ended the video call and tried using the camera.

Went back to the Vodacom shop on the 5th of July. The consultant who helped me with buying the phone tried to figure it out and then eventually calling their repairs shop to assist. They said I should bring the phone to check it out and hopefully they can fix it for me. When I got there I was told that they have to take the phone in for assessment of a Out of Box failure, I was told they have to take it away same time. I told them that I couldn't because it was too short of a notice and my work requires me to have a phone at all time because I'm the 24/7 emergency contact person and I needed time to organise a phone to use to receive calls. Despite trying to come up with solutions as much as offering to take the phone where it needed to go I was told that the only thing that needs to happen is for them to take away the phone.

I am unhappy with this situation because now I'm forced to use a phone which I purchased as faulty
