BookMyShow — Show cancelled by cinema hall but refund not initiated

I had booked ticket at gpr multiplex Hyderabad for jersey at 4 pm but found that show was cancelled after reaching there. There was no intimation from book my show even being informed by cinema hall to them. On calling customer care, they told that they have no information and will update soon. It has been more than 30 hrs but have not received any refund sms from book my show. It is highly irresponsible attitude from them as I have not been assured about my refund yet
