Zomato — refund not received since 2 months

Address:

560047

My order worth inr 2987 was cancelled by zomato on 28th september. I contacted them through email multiple times and received a response 15 days after.
As per the response email they mentioned "i have initiated a full refund of inr 2987 which will reflect in your bank account in the next billing cycle." but they did not mention at all with what is the time period of their billing cycle.

It's been more than 1 and half month since i have received any update or refund from zomato.
