Firstcry.com — didn't get my delivery

My brother mohit choudhary sent a gift which we didn't get (Order no 9651324sn[protected]. But as par the status it is delivered.
The reason we think is..
Around 4-5 months ago, we placed two orders online. The sum for both the things was rs 1150.in the morning the courier boy ashish chauhan came and since i was not fully awake so by mistake i paid the amount i had ready for both the things receiving just one. When i really woke up i called ashish chauhan many times to talk but he didn't pick up my call. I remember the name so well because i tried calling him many times that day. Now, again my delivery was assigned to this boy (I got the message on my phone). This time i didn't even get my thing and the status turned 'delivered'. My brother is trying his end but we both are getting nowhere with this.
