I am a regular customer for jabong. The service they provide is upto the mark. The best part of their site is the coupons. Coupons are applied even for low range products as well. The go javas delivery service is extremely quick and hassle free. They keep you updated time to time about the status of the product. Also you can track the product location once it is out for delivery. This type of service is not provided by any of the online shopping site so far.
Also the customer support service is available for you 24X7. Just like the delivery the refund process is also done quickly and they ensure that you get all the amount you have paid to be refunded in your account.
Overall I would say Jabong is a great site for online shopping
