Onida / Mirc Electronics — regarding smart tv

I brought a onida tv in flipkart. It was a smart tv with 42inch. Within a month it's mother board was failed. I raise the complaint to onida customercare. They given a complaint number it is 1709f[protected]. They said it will be rectified with in 42hours. But it was not rectified for 1 month. I call daily to customer care and ask about that. They say today technician may come sir tomorrow come sir. But not come for 1 month. After a month again raised the complaint to customer care they give another complaint number 1706f[protected]. Then, they said "sir today they will come and solve sir". But not came for 4weeks. Then i called to customer care they said the above. The days were past. After a week i called the customer care. They give another complaint number 1705f[protected]. Then also give a number of onida service center in madurai and vigneshwaran and maharajan. At first they attended my calls and they say today, tomorrow but no one came after few weeks one person came to my house and bring a mother board it was not fit and he gone back. After a month they come and slove the problem. After a days it's remote was burst. Again the complaint raised its complaint number was 1803f[protected], 1710f[protected]. I daily called to vigneshwaran but he refused my calls. Then the problem solve after 2month and 3days and they send me second hand remote not a new one. I still have warranty period they send me a old remote. I ask to vigneshwaran what u send me second hand remote, he said it was send by company. But it also not working now.
