Bad experience after repair

I bought a Bennet Read kettle from Game Potchefstroom on August 2025. In February 2026 the switch failed and I took it in for repair. It was sent to TEVO and according to the repair report they replaced the lid, steam shutoff mechanism and element. Since the the kettle was returned, it gives of a strong and unusual (synthetic/plastic) smell when the water starts boiling and a similar taste carries over into the boiled water. I returned the kettle twice, but TEVO claim that they do not smell or taste anything and refuse to attend to the problem. The result is that I now have a kettle that I cannot use, because whatever causes the smell and taste is most probably carcinogenic.
