Amazon India — defective item due to worst packaging and denied for replacement

Website:

www.amazon.in

Ordered the product 1tb surveillance hard-disk in Great Indian festival offer on 10th Oct 2018, and paid for the product online(prepaid order), got the delivery of product on 22nd October 2018 after 12 days of order. and got the delivery in worst packing, which was torn.
I am underlining the product i.e hard-disk which is a fragile thing. And while purchasing the product it was a replaceable product. Original box of hdd were missing and due to worst packing i.e hard disk like things should be packed with safety, but delivered in the bare polythene without any safety aspect.

When called to amazon the first few day they denies for the replacement as they were stating the product were not available with the same seller who sold it. so wait some day, if it will available we will create a replacement. Then on 30th oct 2018 they agreed for the replacement and they assured me for the rest. But after call disconnection i got the message like they have initiated the return which gives me the refund when product reach their warehouse.
Here amazon cheated me, as they are stating on call that the replacement were initiated by them and assured me for the rest by providing the such detail like the replacement product will be delivered to you once they pickup the product. But after call disconnection they did the different, i.e return instead of replacement. and then when connected regarding the same issue they denies there previous statement which were told by previous agent/customer care executive.
I want the replacement as i got the product on cheaper price on the sale on great indian festival sale,

the procedure, which is not chooses by me, forcefully initiated by Amazon executive by giving the blind/wrong information.
(in whole which they did wasted 20days as of now and counting) as per the timeline ordered on 10oct, got on 12the oct, return initiated 30th oct, + 15 day approx to reach the product to warehouse(if pickuped). then inspection and initiate refund and then credit refund 6 to 8 working day in term of paid via debit/credit card. in whole wastage of 45-50 days and what will got nothing, the amount which paid + Harassment +wasting time,

as i want the product which i ordered which may give some satisfaction at least got the product in good condition after such hazel.
Feels fully cheated by amazon..
