Sansui India — regarding warranty service of air conditioner.

Hello, myself ravindra. I purchased 1ton split ac from flipkart in june 2016 with 4yrs warranty. On september 10, 2019 the ac started cooling problem. I tried call to sansui helpline no. 39404040 and all other service centers which are mentioned in booklet but could not connect. I call flipkart but he asked me to contact sansui. Flipkart gave me a number of sanusi i. E. [protected] where the representative told that they will entertain warranty on that appliances which are purchased in 2019 only, even the complaint was neither registered nor provided any contact or help in this regard, even they refused and disconnected my call when i tried to connect later.
I am very disappointed and upset to sansui as well as flipkart for such response and after sale service. It is my request to please sort out my problem otherwise i will definitely go for the suitable action against the sansui and flipkart both.
