Domino's Pizza — My order is not delivered but the app shows it delivered

Address:

Perungudi, Chennai, Tamil Nadu

For past couple of times, I had a very bad experience with Dominoes.
1. My orders are not getting delivered at all.
2. Even when I am getting my order, it is taking atleast 50 min to deliver and yet I am not getting any compensation or even an apology for it.
3. Items that are ordered (pre paid) are not available at the store.
4. I am getting refund for unavailable items as a dominos app point. Who uses it?? I want refund in my bank account from where I made the payment.
5. When I talk to their customer care, my queries are not listened, no solution is provided to me.
6. I am not getting half the value or service I am paying for, I am very unhappy with the way they are treating me.
