I have purchased videocon 4k 49inch tv and i had a very bad experience with product as well as the service they provide. The tv failed to work properly and even after complaining they never turn up by themself. I also have to keep on asking how much more time you all will take to visit and they took 1 month to visit at home.
The technician was charging as like there is no value for money he took rs 350 as visit charge and 620 for delivery charge and rs 1300 for delivery charge. They are charging like a hell even when tv is in extended warranty then whats the use of extended warranty. I have got fedup with them. Please help me.
