Netmeds — Order not received on Delivery Date

The expected delivery date has passed and I have not received my package yet. The medicines were very urgently required but I could not get them on time. I wrote a mail to them but there's no reply from their end, and the customer care number is vogus, they will keep you waited and not connect with any executive. Can anybody please help me on how to enquire about the order and get them delivered? The amount of the package is more than Rs.1000 and I can't afford this not being delivered.
