Firstcry.com — Wrong product delivered and not accepting a return

Address:

Bangalore

I have ordered small size reusable diaper from MEE MEE, where as delivered product is for NB (New born).
The customer care saying that 0+ months is for new born. while ordering the product it clearly indicates that the size is small. hence I have ordered small size.

The Mee Mee products with same diapers are available with NB, S and M sizes.

since the product details in the app while ordering clearly indicates the size is for small, hence I have ordered this product.

The delivered product is NB. customer care is not accepting the same.

Kindly resolve the issue. I have attached all the evidences.
