Delhivery — For my refund purposes

Address:

Gurugram

I would like to ask for a full refund for the Cream I bought From Mamaearth and the delivery agent was Delhivery

The reason I am requesting a refund is because. I Pay money online and its debited from my account but it wasn't A successful payment but amount was deducted from my account. And then i also pay money to the delivery boy.. But As now i didn't receive my money.
I received a message from your agent that if any money is debited from your account it will be credited to my account but I didn't receive any money..
If i will not receive my money
