Dineout— Reservation at Jannat, Dayal Paradise hotel, Lucknow

13 Oct,2021
I booked table for 2 through their app on 10.10.2021.. they were showing 25% off on payment through their app. So, I uploaded amount on their app. After meals, the restaurant, refused to take payment from their app. And asked me to pay the whole amount (without discount) either in cash or through card. The haven't provided any way to contact on their app or anywhere. So I cannot resolve the matter through anyway. Finally I had to pay the whole amount through my card. After complaning them in their official Twitter account they are not responding.
