Domino's Pizza — Payment issue & store offline

Address:

Delhi

For the last couple of days I'm trying to order pizzas through dominos mobile app/ web portal but every time it shows the stores are offline while they are taking orders through zomato or by call.

I also bought vouchers of Dominos through Paytm but whenever I try to redeem them on Dominos App/web, sometimes the pop-up came that the Payment option is not available while sometime the app disable the option of paying through Gift/vouchers. Also there is no consumer forum of dominos where I can submit my query or complaint. These type of things are not accepted from a giant like dominos.
