Pigeon Appliances / Stovekraft — No Response from the service Person

Hi, I brought a pigeon Rapido Spectro Induction stove recently last month. After few days it doesn't work it always shows error when induction based cooker or any other things. I called a person who is servicing local for pigeon and he said it will be alright. Afterwards again the same problem happened. i asked him he said he will send some company employee to check. But even after few days no one came. More than 20 days passed still it's the same. Poor service even on Chennai Anna Nagar. Please do the needful. Even I call the local service person no response. It is covered in warranty also.
