Hirsch not taking accountability for defected item sold

I purchased a Defy Glass plate stove in October 2021. In January 2025, the glass shattered whilst the stove was being wiped with a wet cloth. I have contact Hirsh several times for assistance, no feedback is given unless you follow up. I was advised that the stove broke due to impact yet there was no impact damage. This was an assumption made by Hirsh and Defy. I was sold an extended warranty which does not cover the specific item I had purchased. No one is taking accountability for a defected item sold me to. Certainly a stove costing around R6k should last longer than 3 years? A technician came out once and took pics. No other tests were conducted or assessments done on the stove to establish the true reason as to why it shattered. Why was I even sold an extended warranty that does not cover the item that I purchased in the first place? How does a stove just shatter whilest being cleaned. Does Hirsh sells stoves that do not require cleaning??? How is cleaning a stove that is not even 3 years old concluded as impact damage? Both Hirsh and Defy are not taking accountability for the defected malfunctioned product that they sold to me. It is more advisable to purchase cheap household items rather than supporting big brands who do not care about client service. R6000 spent on a stove for 3 years, I should have invested in a shoprite stove for R300 that would have lasted me 2 years. Fancy products are not always the best quality. I have requested that the entire unit be taken for some sort of investigation to be done to establish the true reason but Hirsh is not prepared to do that aswell. Where is the customer service? It does not make financial sense for people to be purchasing items from you guys. Especially if it's going to not even last 3 years plus to be sold a cover that does not cover the item I purchased, is daylight *******
