******* service dont buy from Hirschs and Defy

So at home we renovating, we bought a Stove on the 14th of November 2024 which cost R9798 full stove with Oven and a Hob. But because of renovations we only installed the stove on the 5th of December, I cooked on the 6th of December just fine everything was working. Saturday morning when I was frying an egg the stove cracked out of no where. I called Hirschs Springfield, a lady answered and I explained my situation the lady said I need to pay for electrician to come out eAvoca Hills R790 and that the insurance I paid for doesn’t cover glass.Ay I refused and headed to Springfield Hirsch's Homestore To my suprise when I got there Vicky (manager)and Clement said they will book an electrician no charge and will come in 48-72 hours. Electrician only came on Saturday 14 December around 12pm. He checked everything and advised that the stove cracked on it own, everything was done correctly the installation and everything looks perfect, he even explained that the crack is on top meaning its the stove itself not that someone hit the stove yabo. He mentioned that vele Hirsch Springfield Park DON’T WANT TO PAY!!! So I have been calling asking for feedback until this Saturday 21/12 they are saying the issue was the Hob and I told them thats not what your electrician said and he could have easily picked that up and showed us, as he opened the stove. This morning he sent this whatapp saying Defy Service Centre said the issue was that the stone wasn’t cut out correctly!!!! How did their own electrician not see that on site but they can see it on the pictures??? I called Clement, he says I will have to pay for the repair or new glass on the stove which cost R3000.00 Christmas is two days. Am so frustrated, I need my money.
