OnePlus India — OnePlus Buds repair

I bought the OnePlus Buds in 2020 despite issues from friends regarding it's build quality and durability. Now the right bud has stopped functioning and when I went to the service center, they said that since the product is out of warranty, they won't do anything. I called the customer service helpline (on 28/01/2022) and the representative also told me that since the product is out of warranty, which is only one year, they won't do anything about it. They will only replace it if it's in warranty. Upon asking them what I am supposed to do now, he said it's not their issue. The company should mention these things because they are selling a product that will only last one year, and if any issue arises on the 366th day after purchase, I am just supposed to throw the product, because it is useless and unrepairable. This is cheating the customers and I request help from the forum. I just want my device repaired because I can't keep buying new ones every time one part of it malfunctions.
