Amazon India — Return harassment

Address:	Gurgaon, Haryana, 734001
Website:	Amazon india

I had purchased this hair straightening brush which i wish to return. I called the customer care same day for the return & they told me that it's a seller 's product hence the seller needs to accept the return first. So they sent an email regarding the return. The seller agreed for the return but i have to send it back. The customer told me that i have to send it back on my own & the courier charges will be refunded by them. After this i have been checking my email again & again for the address where i am to ship the return product but i haven't been provided with the return address inspite of several calls to the customer care.
I am tired now.
I need help
