Green Chef complaint: Complaint regarding improper service from the technician and customer care

I had purchased green chef stove in June- 2018 and till date it was running fine except plate of one of the burner had got rusted. I contacted your customer care and ordered thr plates at cost of 300rs and one of your technician came to replace the plates. Although he tried several ways but he could not succeed in replacing the plate. Even he tried removing the glass placed upside and he could not do it. Later he taken pics of the stove and bill receipt and informed ur office that it needs to be taken to office for replacement. After he left my wife cooked rice on the same burner and after the rice was cooked the glass exploded due to heat. The reason for explosion was due to mishandling by ur technician.
Later I contacted your customer care several times to convince that these many years the glass did not break and it broke after his visit and its need to be replaced free of cost.
But all my efforts went in vain and ur customer care people did not accept my request. Now I paid Rs 2600- for glass for no fault of mine.
I am writing this mail to expecting fair enquiry and justice to me.
