OnePlus India — One plus gaming triggers

I bought one plus triggers for my one plus 9 device from one plus store app. They had sensitivity issues at the beginning so I contacted nearest (60kms from my place) service center for which I got a replacement. But now the replaced product is also showing same problems. I cannot visit service center every week for this product.

I no longer want this product please refund the amount for this product. It's useless.
