Land Rover Menlyn arrogant disservice

I have been servicing my car at the Land Rover Menlyn branch for the past two years. Last year, I started experiencing issues with my battery, which they replaced. My motor plan expired in July 2024, and I continued to have battery issues. I only remembered to complain about the battery in August 2024. Michelle Botha informed me that since my warranty expired in July 2024, any warranty for parts or services performed while I had an active plan was no longer valid.

On December 3, 2024, my car broke down and was towed to the Menlyn dealership. I was told I needed to pay R3300 for diagnostics before a detailed report could be issued for the fault causing the "gearbox not in park" error message.

A week later, I was informed that the battery needed to be replaced, which was the cause of all the issues.

I would like assistance in resolving my complaint regarding Land Rover Menlyn's refusal to replace my battery, as it should still be under warranty.
