Myntra.com — prepaid product - not delivered and myntra is not supporting

I had purchased 4 tops for my wife on 22nd june 2020, 1 of the top of it was delivered on 25th june 2020, the expected delivery date for all the products was approximately end of june 2020.

On 10th of july 2020 i made a complaint asking for compensation as the products were delivered later than the planned time as it was an anniversary gift.

I got a call from the myntra delivery agent about my parcel on 25th july 2020 and i collected it which contained 2 parcels.

Now there is 1 item which is not delivered and i asked them why isnt the 1 item delivered in todays call, they are telling why didnt you reach out to us earlier and now we cant do anything about the issue.

The amount is prepaid and they're not even ready to refund for the order.

I would appreciate your support.
