Jabong.com — exchange: pickup and self ship

My name : somesh sharma
My order id :109504579832030901903

I was trying to exchange my order because of its size issue as it was delivered today (28th november) but i am unable to provide the pick up address because there is no pick up from that pin code so i tried for the self shipping process, but there is no option for providing the drop in address. I am frustrated due to this site as it is not comfortable. I am now unable to exchange my order.

Please provide an alternative for this as exchange is only available within 15 days of delivery.
