Dear sir,
i have booked this product with id [protected] on 26th may, 2015. but till today they are showing the product fullfillment is in progress and not answering the telephonic call.
I want to cancel this product but there is no other provision on their site so that i can cancel this order.
Kindly help me and take some legal action against this company.
