Frustrated customer

In 2024 November i have purchased a iPhone15 from telkom, the device starting giving faults at 7 months(June 2025) after the contract started but still under warranty. Since then till now October the phone was sent in for repairs 4 times in total, and the past 3 times it went in for repair it has the same fault. Phone came back from repair 2025/10/20 and 2 days later the same fault on the device came back. Telkom wants me to book in it for repairs again and i feel that it seems this is dragging out till the warranty expire in November. Phone was booked into 2 different repair centers and camera replaced twice, but the camera still remains a issue after it was sent away 3 times for the camera alone. The device was purchased for the intended use to take photos due to the camera quality.
