Samsung Z flip 4 disaster!

I am extremely disappointed. I have had my Z flip 4 for a mere 9 months (contract with Cell C) and the screen has broken (gone black/ still operating underneath) twice! I do not have a spare phone and I need a reliable phone, as I use it for work. I had to get myself another phone today, I chose an S23, but I still have 27 months left on my Z flip contract! I've app**** for the R10k trade in, but that still doesn't sort out my remaining 27 months of payment for the broken Z flip. This needs to be sorted out, I believe my Z flip contract should be cancelled with immediate effect and I should receive the R10k trade in amount. A replacement phone would also be great, just not a Z flip please. Please can someone get back to me with a customer centric solution.
