Snapdeal.com — Health medical equipment

I am ordering two set(25 pec. In each set) of 3 layer mask in offer price Rs. 338, Bit today my items is delivered only one set with full amount. That's very disappointed for Snapdeal.
Please send me other one set or please provide the details for send back the received product.

I don't want money. I thought this amount will spend for some irresponsible venture.
