Cinemax — Unauthorized ticket charges and ruthless behaviour

Address:

492001

This incident happened at[protected] at cinemax theatre, I bought 2 tickets and she asked for extra money, as ticket cost was Rs.100 per head, because she added food combo in it. She didn't even asked that if i wanted that combo or not. There wasn't any printed note attached to ticket for combo, just a piece of paper which you have to show at the counter to redeem your offer.
As i did not want that combo so I asked for a fair price of tickets only, i.e, Rs. 100, but she did not and asked me either to take the ticket or move so that other customers could buy, then I talked to the manager about all this and told him that I'll file a complain. Then he just asked me to buy that ticket and he'll return the combo money separately because he didn't want others to see that otherwise everyone will try to claim there money.
I got lucky but they have been cheating since months as other of my friends told me about this and I want this to end.
