Myntra.com — Product I received was defective and myntra refuses to return

I ordered a product -mojri (types of footwear )from myntra by seller NR by nidhi
Rathi

The product when I received I opened it very same day and observed it was defective with one design on left pair was different than the right pair
The footwear had no tags already looked worn out and was dirty
Now when I filed for a complain for bad quality of product and ask for a return then myntra refuses and denies my reasoning and rejects my return in turn blaming me for removing tags and using and wearing the footwear
Which makes no sense
I filed for a return complaint the very same day I got the courier
The product was already in a bad condition and I am being told by myntra that I have used it worn it and I am returning it
They have no proper answer and reasoning for my complaint it’s been a day and they are unnecessary asking me to pay for something that I don’t want and I have not used at all
I have been loyal customer to myntra for sometime now and have no bad record as such and they behave like this with people customers like us
