Zomato — undelivered order after payment

Address:	Jaipur, Rajasthan, 302021
Website:	zomato.in

I ordered food on 27 may 2018 at 11:23 am (Order no - [protected]) and prepaid the amount by paytm but it hasn't been delivered yet even after 24hrs.
The status shows that it has been delivered but restaurant staff is denying any order from zomato and that no one came for picking up the meal.
Sort out my problem asap. I am very unsatisfied with the service and if no action is taken from your side, i will take legal actions.
