Amazon India — Juicer Mixer Not delivered

1. I ordered Panasonic Juicer mixer and paid rs8500
2. On 29th April when Myself and my wife was away I got call from agent that he has come with product and asked for OTP
3. That time my 84 years father was there.
4. After getting OTP he gave a package and left
5. When we returned and opened we found one beach cloth
6. I asked for return mentioning this
7. Agent came and said he cannot take this
8. But in amazon it was mentioned customer refuses return and its lie
9. Every day I am writing my complaint as review but no response from amazon customer service.
