Myntra.com — Return request rejected despite maintaining all tags and packaging

I had ordered a 'LINO PERROS Off-white solid shoulder bag for my mother from myntra. It was delivered on 7 Dec 2021. A return request was initiated on 19 Dec 2021 based on the grounds of dislike of the color of the product. On 20 Dec 2021 return pick up agent came and she convinced my mother that she cant take the product that day so she will pick it up next day (which never happened). On the same day I received a message that my return was put on hold due to Quality Check Failure as it has missing tags or damaged. The product is still with me in the same packaging as it was delivered. It has all the Tags and is nowhere damaged. I do not understand how such a claim can be made.
I constantly followed up with Myntra customer care for the same after which they wrongly categorised my complain under" I have received a damaged product" They kept closing my complain stating that the product received is new. My concern was never the quality of the product. I kept explaining the whole situation every time to atleast a number of customer executives and they kept parroting the same thing and soon closed my complaints under wrong category. On 29 Dec 2021 I was asked to provide the pictures of the tag and video of the product via mail for verifying by one customer care executive Mr Ayush. I was asked to wait until 3 Jan 2022 and that my issue has been forwarded to senior executive Ms Raksha. But they replied the same resolution to my mail also saying that product was delivered new which was never even my concerned issue. Issue was wrong information by pick up agent.
On 7 Jan 2022(just a day after the return window originally closes) they declined my whole return request only stating the product was damaged. On requesting a call back, height o[censored]nprofessional behaviour was shown when nobody from their team could provide me the exact details of how they found it to be damaged or why did they cancel the return request. They wont even send any agent to verify the claims or atleast re-check the product if they want. How did they find it to be damaged then?
This was simply a case of misguiding by the pick-up agent and then all the inconvenience caused which they kept justifying under random wrong topics as "product is damaged" or "tags are missing" etc.
Its has been more than a month around this issue now and I am unable to even make a return request again as the window is closed. I have all the proof that the product is just as it is and fresh and I am being wronged here based on baseless claims.
I just want return pick up of this product that I am stuck with now and its refund. I urge someone to please help me resolve my concern or atleast guide me with suitable course of action.
