Consumer Redressal

I had bought an Intex Aqua phone . They are selling the phone by saying the memory is 4GB but the actual phone memory for apps is about 1 GB and I cannot download apps even after installing a memory card of 8 GB. It is a clear case of misleading the customer since even when I have around 6GB of memory I cannot download apps of size 140 MB. Further the phone memory is full of OS,technically Intex has willfully hidden information from customer.
