HDFC Bank — Food card lost

Address:

Chennai, Tamil Nadu

I have lost my HDFC food card in Dec 2014. Food card number is [protected]. I reached out to customer care and blocked the card. While blocking, the balance in the card was around Rs.850 and i need to get the money back. I reached out to the CC but the call was always getting cut in the middle. I am fed up in trying them and i need to know the procedure of getting the money back.
