Mellerware are selling unsafe products. BE CAREFUL

I Purchased a Mellerware kettle on Takealot last year the kettle arrived and and worked for only a week, I then sent this kettle back for a swop out, I then got the same model of kettle and used for just over 6 months the kettle then shorted out and burnt a hole in the base, I sent this back and Mellerware and Takealot refuse to honor the guarantee, Mellerware states the kettle was turned on without water in it which is untrue, but they are admitting that their appliances do not have basic safeties built into them to prevent fires, essentially they a selling ticking time bombs that have petonial of injuring people.
