Jabong.com — return policy

Hi,
I have requested for a return on 5th october. And i self return my item and send all the courier details to the customer care on 6th october. But on 16th october i got a mail from jabog saying that they are closing my return request because i didn't provide any return documents. I filled a google doc and attach the courier slip also with that. Then on what basis they are saying that they didn't get any information. It is like a great cheat... How can i trust this site to buy items... I want my money back. It costs 1500. My order id [protected] and returning id : 49321246
