Myntra.com — Product being shipped back to me

I ordered U.S. Polo Assn. Men Black Solid Xylon Walking Shoes on 16 January 2021, from Myntra.

I received them on 19 January.
I wore them to see if it fits me and then put it in the box it came in.

On 20 January I was getting the same shoes for 2299. So, I ordered them and filed return request for the previous ones.

I packed them as it were delivered. They got picked up on 21 January.

I received the 2nd ones on 24 January, better packed than the previous ones.

On 27 January they notified me on orders section that those shoes I returned has failed quality check.
On same day I called their customer care service and told them about the situation. They filed some sort of complain and assured me they would take necessary measures to avoid me any kind of inconvenience.

On 28 january, Myntra app notified me my query has been resolved and those shoes, which I filed return request for, are going to be re-shipped back to me.

Again, I called their customer care. And they again filed some sort of investigation to be resolved before 2nd February.

They said that those shoes are used, but all I did was wore it once on the day they were delivered to see if the size fitted me. That was barely for 3 minutes.

I want my refund.
I can't lose 3200 for nothing.
