blinkit - Blinkit does not refund cancel order money to original source

I choose a wrong address and had to canel my order in blinkit. Blinkit does not have an option to refund money in original source. It gives you a coupon code which expires in a month and you have to use all the amount in one order.
In my case, since I was in my hometown for that month and there is no Blinkit there, Blinkit just took my money. According to Indian law, such apps has to have an option to refund to original source.
