[Resolved]  HDFC Bank — Amount debited, not refunded

Address:

Chennai, Tamil Nadu, 600078

I tried booking bus ticket through redBus.in on 6th Oct 2016 using my HDFC debit card.
Rs. 4250 got debited but the ticket was not issued.
When i tried to contact redBus about this transaction through customer care there was no response and then I had to try contacting them through Facebook chat only (attached screenshot of conversation), they informed me that the transaction wasn't captured at all & they told me that it will be automatically refunded in my bank account within 7 bank working days.
I have not got my refund yet.
My account statement is the proof I have for the debited amount. chq/Ref no:[protected]
