Nykaa.com — wrong product sent and they are not refunding the money

I ordered for bronson professional 2 in 1 combo hair straightener + hair curler which was delivered to me on 6th dec. When i checked the product the packing in itself clarified that they are selling a local product and a sticker of bronson was sticked on the packing. The website of nykaa shows this product under the brand bronson but when i received the product i was very disappointed with a local product being sent to me. I opened the box and no where on the product also the name of brand bronson was mentioned. So the first deceit they did was selling local product under a brand name on their website. I immediately on the very same day (6th dec) requested for refund of the product. On the product description it is clearly mentioned about the easy return and refund policy. These people do not even have realistic drop down menus to give reason for refund. For 4 days nykaa did not bother to reply to my concern. On 10th dec nykaa emails me that the refund request is not accepted with the reasons which do not apply to me at all. I requested for refund the same day, i did not the product, it was not a personal care appliance that any hygiene issue comes up, anyway it is a hair styling took and i haven't used it even. Also there is no one who came to pick the product so where does the original packing thing came up which they mentioned on email. They reasons for not initiating return and refund were baseless. After that i emailed them 3 more times but nykaa is not bothered to reply back to the irated customer. Nykaa is not even bothered to service the customer for sales, forget about their after sales service. Worst online service provider nykaa is. There are other online shopping websites which are doing so good. Nykaa doesn't even call the customer and emails that the customer support executive contacted and asks to rate them. This is so bad on nykaa. I need refund of my amount because you are making fool of a customer, showcasing product on your website which looks branded but when the customer receives the product it is actually a local product. Moreover, rather than speaking to the customer about the concerns you put standard pointers on email and close the ticket and after that you are lost and do not even bother to call your customer or reply on email to the customer. Why will a customer come back to nykaa if this is the way their after sales service works. Please refund my money. Product is hair straightner and hair curler and product number is nyk[protected]
