Snapdeal.com — Product return related issue

Address:	Panchkula, Haryana, 134109
Website:	Snapdeal.com

I ordered shoes from this website! Since the first day i recieved those shoes, i lodged a return request for the shoes as the shoes are not of my size. A message came at the app, that my item will be picked soon. But noone came to pick the shoes. They are still with me. I am writing so many emails to smapdeal, but no one is replying.
Now a message is coming on the app, that return cannot be placed, as 7 days return policy is over! The delay in return is due to the website, not because of me! This is the worst website, i am really irritated! Poor customer service
