Ibibo Group / Goibibo — Not getting the refund

I'd called to the customer service centre for the information of refund. As per the track status available on goibibo app, the amount is credited but I didn't recieved any amount.
Since the date of booking was 28th September, 2021 and journey date was 20th Oct, 2021. How much time will you take to refund that amount?? Your service is very slow. Plz refund it asap.
