Boult Audio — Delivered Anathor used earphones instead of my earphones sent for repair to avail warranty

My left earphone is not working so I raised a ticket. My ticket ID is 00464737, and posted to the manufacturing address on 6 th march and I got the product today it is on 18-3-22, I eagarly waited for 12 days for earphones and now I got a used old other red boult earphones instead of my black boult earphones. Is this the warranty means from the company sending an already used product, then why is this warranty and all...

I demand you justification for this
