TTK Prestige — Wet grinder

Address:

560036

I was sold a defective grinder whose grinding stone became defective after using only couple of times. When complained, they didn't have spares and had to follow up for 4 to 5 months to get the spares. After few months now there is another major defect which we have been following many months. Now the warranty is expired. All this is due to the delay from ttk prestige's support and service. What are the options available for me to get justice.
