No refund from PVR for 3 months

No refund from PVR for 3 months
I had booked a show on April 11th and got a call few hours before showtime from PVR ampa mall that the show has been cancelled due to technical issues. They promised a refund in 7 to 8 working days. It’s July 8th now and I still haven’t received the refund. Multiple calls and multiple explanations and multiple 24hrs later, PVR still has my money. Pathetic service
