Snapdeal — Order canceled due to cheap price offered

Address:	Kota, Rajasthan, 324005
Website:	www.snapdeal.com

I ordered a digital camera on 15th june at snapdeal at the price of rs. 7460. On other shopping site "paytm" offering same camera @ 8400 with 7% cash back = rs. 7812. But by checking on snapdeal i ordered this canon 275hs on their site @ 7460/-. And make the payment through freecharge wallet. I had a function on 19th june on my sister's home. So i want directly delivered this at her address. Regarding this i also sent an email on [protected]@snapdeal.com, but they are not accepting mail through help portal. From last 4 days i am continuing checking my order details and it showing that the order is "prepared to dispatch". It means order is available and packed.
Now snapdeal closed my order and a representative says that my money will refund in 24 hours in my freecharge wallet.
How could they do this to me. My gift canceled without delivering. I had a function on 19th. How could a function can complete with camera. If they don't show the price of rs. 7460 then i will order that product on paytm. But now the camera price showing rs. 9555. How?
A direct loss of rs. 2000 and my image in front of my sister and her family.
