Swiggy — refund not initiated for money debited but order not confirmed

Website:

swiggy.com

On 30 september, 2018, i ordered food from swiggy and the money got deducted from my bank account but the order was not confirmed from their side. My order no.#[protected]
I tried calling the customer care no. but there is no option for this kind of query to talk to the required person . There used to be a chat option in the app but now it has been replaced by call which no one receives.
I am completely unsatisfied with swiggy's refund policy.
