Amazon India — Indulekha Bringha oil

Address:

Mumbai City, Maharashtra, 400098

I had procured 2 bottles of Indulekha bringha oil from Amazon, I compared the product received with the indulekha bringha ooil bottle which I had separately procured from a chemist shop,
(1) Indulekha is manufactured/ marketed by Hindustan Unilever Limited (HUL), however the product I received from Amazon does not have the name of HUL as against the one I had procured from the chemist
(2) Secondly the content in the orginal bottle procured from chemist has milk (as mentioned in the product details), however the product procured from Amazon doesnot mention any such details
This seems to be a fake or a duplicate or an adulterated product received by me, I spoke to the customer care who said he would send the complaint to the internal team and credit the money paid by me, however he said he would not be able to revert to me on why such a flaw has happened ? who is responsible to ensure that the original product reaches the end customer ?
I am not at all happy by the response given by customer care
