OnePlus India — OnePlus buds pro

Address:

OnePlus authorised service centre Madurai

I bought OnePlus buds pro on Amazon by April 2022. Recently my buds pro right ear piece not working properly. Battery drained soon and mic not working.
I went to authorised service centre Madurai today. They received my product. Later they told warranty replacement not available due minior scratches. There is no visible dent or scratches.
I am really disappointed with the after sales service and customer support.
