Hello, @Anandhkumar .
As Shopify is software used by merchants to build their businesses upon, I would have no access to information regarding your order. However with that being said, I do completely understand to order something online and have it not arrive is always disappointing.
When was this order placed? The easiest and best way to sort this out would be to get in touch with the store directly if possible. Are you able to reply to any emails from the store, the order confirmation email for example? Does the store website have a contact phone number, email or social media link?
Once at least 30 days have passed and you have neither received the item, nor had a reply from the merchant, then I would advise reaching out to your bank for their advice on next steps to take. If you feel concerned this store may present a threat of fraud, you can use our "Report a merchant" function here. Thank you.
