Zomato — money deducted twice but payment failed. error shown "parameter missing"

29 april 2019. I ordered cake worth rs 493. I paid through sbi net banking. After the payment was made the app showed error parameter missing.

And the only option was the back button which cancelled the order. I thought it to be a one time problem again made the payment. And the same thing happened. Finally i made it a cod order.

So now rs. 493x2 have been deducted from my account. I request that the money be immediately transferred back to my account.
