Billiard Snooker & Pool Point - Shop Owner denied pending payment for the services

Hi,
This is a case where the Shop Owner denied pending payment for the services I used. Following is the details of the incident.
At *:**pm on **th November, **** me and my younger brother went to Billiard Snooker & Pool Point which is situated at ***/*b, Mir Singh Palace, Bank Street, Munirka, Delhi - ******, Munirka. We paid Rs ** to play for an hour but due to some unavoidable reason we ended up playing for half hour. We requested the owner to pay us back the left over amount but he very rudely said that he doesn't pay back. I asked him to give me this in writing but he denied and threatened me by showing his "Crime Branch Identity Card". I asked him for his phone number but he denied that as well and started shouting at us.

You may ignore this case as it is not a high value case but to me it is still counted as cheating and fraud. There is no Written instructions in his entire shop stating that he doesn't pay back. As a customer, I am cheated.

I will take this incident very seriously and if your department cannot handle this, please do let me know before hand so that I can explore different options, but this is assured that I will make sure that people like this shop owner must not be in market cheating people. I could only manage to take the banner image. Please find attachment.
