Shoppersstop.com — received 1 curtain when I paid for 2

We when to shoppers stop soul space arena in bangalore and physically bought 2 curtains. They gave us one 7 inch and another 9 inch. Then we went back and asked to exchange the 9 inch to another 7 inch. They said they dint have and there was nothing they could do.
Then they only suggested we place an order online and have it delivered home.
They did it for us and the parcel said quantity 2 but they sent only 1 curtain which got delivered to us.
Now that packet is so small it possibly cant fit 2 curtains they are arguing that they have already delivered both the curtains.
This is the most annoying thing shoppers stop can do. Ridiculous for one curtain!!
