Disappointed at SAMSUNG SA

Good day

I have taken out a contract with MTN over a year ago for the Samsung z flip flip. the device had come with a one year warranty (screen damage). The care September plan expired on the 7 September 2024. A few days after this, the screen cracked without even falling. Are these phones meant to crack a few days after the plan is over and SAMSUNG does not even want repair considering that it was only a few days the plan had expired had this happened. I am told I am liable for the costs of repairing. Now, I am stuck with a 36 month contract, cant use the phone and still have to pay toward my contract and also 7k to fit the costs for repairing. At least consider a discount on the repair. I have even emailed Samsung twice with no response.
