Firstcry.com — missing of d product in the packaging

Hello,
I have ordered pampers small and pampers xl on 26th of february 2019, each two in quantity. The item were delivered on 28th february 2019 and were received with full payment i. E. 2503 by one of the family members as i was out. When i checked the products pampers s were two in quantity but pampers xl was one in number though 2 is mentioned on the receipt.
I havent opened any of the packets. They are the same as they came from the company. I dont want any reimbursement but the missing product should be given.

Thanks you,
Ankit saran
