PVR — Making customers buy instant popcorn worth 150 rupees along with movie tickets stating that it's a "mandatory offer".

Address:

PVR, DIAMOND PLAZA, KOLKATA.

I had bought 2 tickets in PVR Diamond Plaza, Kolkata, for Kashmir Files. The price should have been 160 + 160 = 320.
Show Timing: 4:50 PM. Date: 30.03.2022.
I had visited PVR Diamond Plaza in person to book the tickets.

Instead, they took 470 from me (320 + 150), the 150 was for a popcorn box. It has 15 instant popcorn packets inside it, 10 rupees each.

I paid 500 rupees in cash and they gave me 30 rupees back.

I realized that this popcorn was not exactly on offer. They were forcibly adding it to the tickets.

I asked the person at the cash counter to remove the box of popcorn (and the price of 150) as I did not need it.
It was not ready made popcorn like they sell in theatres, I would have probably understood if that was the case.

I was told that, it was an "offer" that I had to accept if I wished to buy the tickets and that it was non-refundable.

I have received confirmation for the tickets via SMS. It has the 320 mentioned on it.
But no confirmation for the extra 150 that I paid has come in yet.

I was told that there is a "technical issue" going on and the proof of payment (via SMS) would reach me.

If there was an offer, there would have been some sort of display at the counter. There wasn't any.
At least a SMS confirming my payment would have reached me. It didn't reach me either. Total fraud on their part.

I am not aware if the amounts collected from the sales of these unnecessary popcorns are actually going into someone else's pockets. Because the packet of popcorn has 4700BCPopcorn mentioned on it.

I would like to state 2 things:
Either I received a proof of payment for the extra 150 that I was made to pay.
Or I get the 150 rupees back (they can take the box of popcorn back. I do not need it. It's unopened).

Hope to get a response soon.
