Amazon India — send defective product.

Sir/madam
I ordered pop up toaster from amazon. It did not work properly so i called amazon's customer care on 26th july 2017 regarding my concern. The customer executive told me that we will send a person from amazon to your home and he will picked up your product. So i packed it.
After 3-4 days i do not got any response from them.
So i again called them on 2n august 2017, the amazon customer executive told me that we have not any records regarding your talks with amazon customer care executive held on 26th july 2017 and the deadline for raising return or refund is also passed. But our team will contact you within 24 hours. But till now i do not got any response from them.
Please help me. Amazon is trying to deceive their customers.
