Product not replaced and no refund

I purchased POCO earbuds from an offline store approximately 10 months ago. The product has a 12-month warranty, with around 2 months remaining. The earbuds have developed a problem, but the company or seller has refused to repair them under warranty. Instead, I was offered the refund amount as credit in an app. I do not want app credit. I request either a replacement with a new product or a refund to my bank account. Both options have been refused. The current price of the product is approximately twice the original purchase price. I request assistance in obtaining a fair resolution under the applicable warranty terms before the warranty expires. I can provide the purchase invoice, warranty proof, and communication with the seller or company. Please help resolve this complaint.
