PVR Cinemas — Big scam and fraud at PVR food court

It's been 3-4 times now that I am being charged extra without my consent and not even getting a bill. Also, they don't give us what we order unless we ask for it again and again. They ask for phone number and tell us that you will recieve the bill in 5min and tell us to enjoy the cinema but the bill is never sent in the message. I have also complained it at their website but never get a response. It's a cheat and violates consumer rights. Strict action should be taken.
