Amazon India — where is my order?

Website:

amazon.co.uk

After chasing numerous times and contacting amazon customer service, i have to say amazon india has one of the worst customer service. I placed order last week and funny enough the status says it is delivered. Fact is i haven't received anything. Amazon said they have complained the courier service and asked them to contact me. So i just checked what the contact number is. And to this i get a reply "i am really sorry for the inconvenience that we can't able to see the courier number which you received."
I am not even going into the grammatical mistakes here but this lady called dhivya was totally clueless. I live in the uk and i cannot even compare the service between the 2 countries.
I am still sitting here without a sign of my order. Doing countless chasing of my order.. Still unsure if i will ever recieve it. At this point i am not bothered about the product just want the money back.
