Samsung — Complaint about damaged product

Address:

4, govind sankul, krishna nagar, panchavati, nashik, Maharashtra

I purchased Samsung Qled 55 inch TV. After some days it started showing 4 green dots on the screen. Their visibilty is increasing day by day. We called samsung customer care they visited and examined the product and they said they don't have the spare part of that model so that they can't fix it and they can provide us with the 80% of the refund amount from the total amount. That means they will deduct 20% of the money. But as per the ethics if they don't have the spare part and can't fix the product then they should provide us with the full amount of the product.
