Lenskart — Order is undeliverable because of damaged package

I placed an order for two glasses on 8th Dec, and recieved one of them yesterday. The second product tracking details say that the package is damaged and is undeliverable. The customer care service of Lenskart barely responds. But now lenskart will say that they'll refund half of the amount to me and when I'll place a new order they are going to take the complete money. The package is damaged and it's not my fault but why should I suffer? Please resolve my issue. I need my glasses as soon as possible.
