Samsung — Samsung fold 4 display issue

Address:

C-5, First Floor, New Krishna Park, Janak Puri, new delhi 110058

I have fold 4. All of a sudden it's display stopped working and a black line appeared in the center. I went to the customer care and they said that I wll have to pay for the display . My phone is in warranty and I have seen that issue is there in this model. It's company's fault. Two known ppl have faced same issue. I saw on internet that ppl r having same display issue. I am sending my job sheet and it's a request that plz fix my display. Its in the name of Arav, my son. If this type of issue is coming in such expensive phones then Samsung should stop producing such models. Please fix my display and I am not paying as it is in warranty.
