Paytm Mall - Samsung Galaxy S9 Plus mobile received without accessories - PAYTM denied return

Hello, AVIJIT this side. My product order id - ********** My contact no - +** ********** I have ordered samsung galaxy s* plus from paytm mall on **th october ****, i had received the product from courier on **th october, later after unboxing i found that there are no accessories inside the package. I had taken a video during unboxing as proof and clicked some pictures of the same. Later immediately i have raised the return request on the same day after escalating the issue to customer care team over phone. After so many followups around **th november they refused to pick up my incomplete device and denied the return request. Now they are saying they had sent me proper product, i have shared all pictures and unboxing video, still they are not doing anything. Unable to use my device without accessories, the phone is not turning on without charger. I have doubt also theres any defect on phone or not. Paid rs.***** for the product on some unprofessional ecommerce website, so much harrassment already faced by me. Everytime they are sending same system automated mail that they wont be able to process the return request. Sent them over **-** mails, Have all evidence with me. Kindly do the needful immediately. They are simply looting and fooling customers, no proper return investigation has been done from their end. Unprofessional seller tagged as brand authorised seller. Such a pathetic shopping experience with paytm.
