Reliance Fresh — Cheating and not providing the billed cheese pack

Address:

Katriguppe Bangalore 560085

Bought 200 gm of Britannia cheese and got it billed along with other items. However, after scanning, I was not given the cheese pack. In a hurry, I exited with all items and immediately realised that have left it behind. When I returned immediately after 1 min, I was told that it was my problem.
I have a feeling that the billing staff kept it to themselves and I have been cheated.

I want the CCTV cameras to be checked.

Attaching the invoice and expect a prompt action and response from reliance.
