Amazon India — complaint about no delivery of godrej washing machine

Address:	180013
Website:	Amazon.in

Sir i ordered 7kg fully automatic top load godrej washing machine from amazon.in on 28th october 2018 and i paid through atm card. My order was successfully placed and i got delivery date between 31oct to 8thnov, as i wanted it on diwali.
After 2-3days my delivery date was vanished from app.
I tried to contact customer care they told me that now it is out of stock and i need to wait for new delivery date. I waited and then again contacted them. This time they told me again to wait and told me that my product will be delivered before or on 8th nov. As i was not getting any delivery date i contacted them again and told them i need the product they told me that we don't know when it will arrive and told me to wait.. Also i told them i will complaint against them.. But they told me that they can't do anything. I asked to talk with their manager but they told me he also can't help. The last person i contacted told me to wait for two more days on9-10nov.. And on 11nov they are telling me to apply for refund.
They mentally tortured me and made fake promises and told me to complaint as if it was normal for them. I asked for compensation but they told me that they will not give me any compensation. The occasion on which i planned to buy product for gifting my family has gone.. Till now i have not received my product.. Please look towards this matter.. And serve justice. I demand refund +heavy compensation for my wastage of time and mental balance. I have recordings also but format is not supported.
Thank you
