Once you raise a request, you get an email and an SMS confirming that your request is being processed. Based on the item, either your request automatically gets approved or you are contacted for more details. In case your request is approved, the item is picked up from your address and you get a replacement or refund as agreed with the merchant.
Moreover, you are also given the convenience to track the status of your return request instantly from the 'My Orders' section of your Marketplace account.
