TTK Prestige — Prestige marvel gas stove glass top bursted

Today, i was working at my kitchen on Prestige marvel 3 gas stove.
Suddenly the glass top bursted and the glass shattered everywhere.
I got injuries on my hand. The prestige costumer care is telling me that it isnt their product fault.
What? Are you serious. The glass is of so bad quality that it heated and bursted.
