Jabong.com — not able to return the product in the same pincode i have purchased

Address:	Thrissur, Kerala, 680651
Website:	Jabong

I had purchased "brown derby boots", lee cooper from jabong of size uk 10. Unfortunately it's large for me. I need the size uk 9. I tried for return on the same day, but none of the pincodes including my purchase address pincode is working. This is so uncomfortable for a customer to try every pincode the state has. This shows jabongs lack of consideration to whatever they claim as easy return options.
Many people might end up not returning the product feeling helpless. But am gonna make sure you guys will face the consequences if you continue to play this unethical strategies of sales.
Make sure you rectify this problem at the earliest.
