I buyed Micromax Canvas A96 from frazer town-Bangalore mobile store on 18/04/2014.

I was expecting 1GB RAM, but this mobile has only 512MB RAM.
When I uyed they told its 1GB RAM and sold it to me, after installation of some apps I found mobile was slow so I check the problems and reviews os the handset but I found it was only 512MB RAM.
It was shocking for me that the mobile store person gave a wrong information..

Now who is gonna pay for my loss ?
Is there any way to buy 1GB RAM mobile(I feel canvas Juice is better).
