Ibibo Group / Goibibo — Refund problem

I have booked my bus ticket in Rathimeena travels from goibibo app on August 1st for travel on August 11th morning 6am from Chidambaram to Chennai. And I tried to cancel my booking in goibibo app but I can't able to cancel it so I have called customer support In that I can't get to talk with any customer service person instead GIA chat there, I cancelled the tickets through that automated chat on August 3rd it said you will receive message regarding penalty charges but I didn't get any confirmation message on my cancellation.I have checked the same tickets in goibibo it was shown as available so I thought tickets were cancelled and I have waited till 7 days after my cancellation but I didn't get any refund money. In goibibo app it is showing as completed trip. I don't know what they are doing with that app. Very much disappointed. App isn't working properly, no proper customer support. Completely waste!!!
