As I have ordered a product from nykaa and I was ordered last month and was not delivered to me a was delaying again and again and then at last it was returned to warehouse without any delivery attempt was made and no contact was made to me as i wanted the product on emergency it was not delivered to me on time then I have raised complaints many time but then they again ordered the product manually and the earlier order amount was refunded to me but till now the product is not delivered to me and again the same situation is happening it is in my location from 12 July.
