Nykaa.com — jockey panties pack of 3

Nykka has a very ### service where they did not even accept to cancel or replace the wrong product delivered to me.
The CUSTOMER CARE is giving excuses that they cannot replace jockey products. But they are unable to understand how will a customer use the wrong product.
The colors and size of the product is wrong and hence my money will go waste. It was a big mistake to shop from nykka. And i want to sue the company for causing such problem to me
