D-Mart / Avenue Supermarts — non delivery of order

Frauds. Took order 5 days back and didn't deliver. Now i have to follow up for refunds. Such group of cheats is a shame at the time of national issues. They said that they are taking group orders of more than 12k of minimum value. I needed some products urgently and preferably online. I made a payment of 12.6k. This is fraudulent that inspite of taking advance payment they didn't even bother to inform about late or no delivery status. Moreover i had paid delivery charges of around 400/-.
