Intex Technologies — after sales services not provided

Respected sir/madam i am neha baikerikar. I had purchased intex led-5500fhd tv from mithun enterprises on 19/08/2016. The tv came with 3 years warranty. After 1 year the tv got some major problem so i complained about it and after that the technician came and repaired the tv then after two months tv again got major problem in the display, the display was turning off after sometime automatically so i again complained about it but i didn't get any response from the company's technician so after around 3 and a half months the dealer replaced the tv with the same model but again after 5 months the replaced tv got problem in the display and the dark patches are visible on the screen so again i complained about it but i didn't get any response until now, i have complained about it on 10/11/2018 and the complaint number which dealer gave me is[protected]. So i tried contacting the dealer many times but i did not get any response from the dealer until now so i'm mentally disturbed. The intex's tv is a very bad product and i got one or the other problem after some days again and again and their after sales service is also very bad so i kindly request to refund my full amount (Money) back which i paid for the tv which is rs. 50000. And i don't want any replacement of the tv with any intex's product. I have attached the product bill. I had previously complained about this on https://consumerhelpline.gov.in on[protected] at 21:42:46 but i did not get any reply from https://consumerhelpline.gov.in so i'm complaining here again and my grievance number is 1120323 and my phone number is [protected]
