Amazon India — seagate 5tb hdd

Address:

Bangalore, Karnataka, 560058

I've ordered for segate 5tb hdd, where the amazon india has cancelled my order without my knowledge the price for that product was 2999 i thought there was an offer on this product and i booked, so i need to know why they have cancelled my order and i need that product for the same offer price
This is the message i got when i placed my order
Confirmed: order for seagate backup plus.. Is successfully placed & will reach you by 25-sep. Track:http://amzn.in/7igTndi or give missed call to[protected]
Message when they cancelled
Your order for seagate backup plus slim 5tb port... Is cancelled. If you have already paid, refund will be initiated shortly. Details: http://amzn.in/8eqtkpa
If they face any technical problem that's your mistake not mine
I even called for customer care they r saying that the product is not available so they cancelled
I feel so low after amazon did this
