Zomato — order didn't delivered but shows delivered

Address:

To whom so ever it may concern

I place an order from Sethi barbeque at 8.34 pm. But I didn't receive my order. I tried to call Akash (the delivery boy) but the phone was continuously switched off. when I contacted the restaurant they said that the food has been picked up an hour ago. But I didn't receive it. And now I am getting the message that my food was delivered. This is how you treat your customers no chart support the delivery boy number was switched off as well as the customer care service. I want a full refund as I didn't receive my food.
I hope you will understand my situation and take action accordingly have mailed my complaint 3 days ago but still, there is no response. i
