TTK Prestige — induction cooktop not working

Address:

Mumbai City, Maharashtra, 410206

I have purchased a induction cook top. After checking it is showing like E3 error. When I contacted customer care they have told me this error is showing because of high voltage. So i have submitted to nearest service center. After one week he returned back. After that when I checking it is showing again E3 error. When I talked to customer care they are told me the service agent will to come to your home. It is 5days completed nobody is came to my home. Next time I will not by any prestige product. My contact number is [protected]. It is a bad experience for me.
