TTK Prestige — Three burner L. P. G. stove

Address:

Plot no 38,SIPCOT Industrial complex, Hosur - 635126

I purchased a three burner L.P.G. stove on 12.02.2021 from Pathak Trading, P-20, Radha bazar street, Kolkata -700001, shop no. 4.
From the very first one gas control knob was defective. The service man came and repaired that. Again after one month, another knob becomes defective. On February 05, 2022, I lodged complain and again on 10.02.2022 in Prestige customer care but no service provider has contacted me or turned up yet. In the occasion of previous complain also they behaved same.
Please note that the warranty period for this product is two years.
