Myntra.com — Refund of Wrongly supplied goods

I hve placed order No. 1154882, 4862237, 3470701&1154796 on for 2 Shorts & 2 T Shirts for male and made payment of ₹ 2094/- alongwith the order.
I have received a parcel very late than they informed, on 26.10.20. Packet i.d. [protected] and invoice no. 10621C[protected]. On opening the parcel, surprisingly I found BIBA Brand Ladies Kurta. Immediately I informed Myntra and they asked to upload picture of profduct tag which U have uploaded after so many try as it was not accepting.
Then I received message that they are arranging for collecting it back and shall refund the amount. I have returned it. Surprisingly, I have received refund if only ₹ 698/- again full bill amount of₹ 2094/-. I had requested them so many times by written them and also talked to them thrice. Unfortunately everytime they simply told me that it's under our investigation and shall revert back within 48 hours. Lastly I talked to them a week back and I am still awaiting for their positive reply and refund of balance amoyt of ₹ 1396/-.
Please do necessary and arrange to get me refund at an earliest.
Thank you.
