Complaint regarding Flipkart wallet refund money

I had purchased a shoes worth rupees 1567 from which i had paid 1434 from flipkart wallet which was earlier refunded on purchase with no option left rather than flipkart wallet option. i had to take this amount of rupees 1434 in my flipkart wallet. Now this amount of 1434 is not showing and flipkart team says they will not refund this amount as i had not utilized this for an year. Requesting your team to intervene and resolve this matter after all 1434 is not an amount which i should get back.
