Netmeds — Money deducted but neither order had been delivered, nor a refund had been issued

I have placed an order in Netmeds, on April 17th, but the medicines aren't delivered. The next day, I receive a notification stating my order has been declined without stating a reason, and I didn't receive any refund till now. Even the order has been vanished from the list of orders. I had tried contacting them several times, but no response. I had placed an order again, after two days, but cancelled it immediately, with the fear of loss again. I had attached the order details about the re-order too. I had ordered it on 19th, but the delivery status is showing between 18th to 19th and I don't understand how it possible. I hope this complaint could be seriously considered and been resolved, as there are many complaints on the similar issue, left unattended since long.
