[Resolved]  Greendust.com — Not received the power bank ordered nearly 6 months ago

Address: Bangalore, Karnataka

I had ordered and paid for a power bank from greendust sometime in june/july (it's been so long... can't even recall it clearly).
I have not received the product till date.
Tried contacting the customer care on two occasions.
On both the occasions, they assured that i will be getting a communication about this the next day.
But no one called.

I want sue them for this mistrust and the torture that they have put me in.
