Myntra.com — Purchased picked up and refund not processed

Date of Incident: 11.09.2021
I have purchased earring on 10.09.21 and on same day I requested for return. Next day the packet was picked up from my home by myntra executive and on same night I received call from him that the packet was misplaced from him and he will pay the amt. Call was received from myntra no only. He never contacted again hence I registered complaint to myntra against this issue. After N no of complaints and follow up myntra not responded and not refunded my money. I have shared call recording also but no response from myntra. With this issue I have spent lot of time and energy hence I also want compensation of that. I deserve more refund than purchase value of invoice. This is the question of ethics.
