TTK Prestige — Induction not working, Extremely poor service

Address:

15, HBR Layout 3rd Block,, Krishna Reddy Layout, Kalyan Nagar,

I had purchaed a Induction Cook top Pic 2.0 V2 and since 22nd May my power has been tripping off when I connect the stove.
I had placed a complaint on this Prestige helpline no: [protected] and I was assured that the Service person would come by 2 todays maximum, but nobody called or came, on the 3rd day when I called they assred me the service person would come on that day but Nobody came. Then I called onthe 4th Day and spoke to Hani at around 8:30 am and she assured someone would come today and she would call and confirm by 11 am. She didnt call by 11 am after which I call the number and spoke to Azad at 11:30 and he gave me the Royal Enterprise Sanju [protected], the person who spoke was Kumar and he is telling that the Service person will come by tomorrow.I have no keen intrest in keeping this induction stove due to the poor service provided. Please tell me how to go about it.
