Zomato — refund for duplicate payment

I had ordered a food from tikka junction at janakpuri on 26th jan'20 through zomato app, at 1st attempt it showed that payment failed however it was deducted from my card, than i made the payment again. But order got repeated and i got a call from restaurant as well mentioning the same and they agreed to cancel 1 of the order. Now i am waiting for my refund of rs 901.40. Tried multiple times to reach your customer care unfortunately all numbers mentioned at google are invalid or not working. Please make the refund at the earliest.
