Flipkart — Not refunding money for damaged refrigerator

Website:

Flipkart. Com

Have ordered refrigerator, and got damaged one with different colour.
Dint even confirm with me before delivering the different colour.
& It was having dent on side they assured for 20% refund.
Till date dint get anything.
And when calling to customer care they are saying we can tsee any request for refund bcoz product itself is not delivered and sry for delay in delivery... Such bad system management.
And now after 1000 calls and same conversation they are keep saying will check . Not refunding money and causing daily headache
