Rajdhani Express — not getting food in train no 12433

I was traveling with one of my colleague on 17.12.2018 in pnr no [protected] in train no 12433. I have boarded train from gwalior jn to agra cantt. Though i had paid for food but it was not served during my travel. We made request to catering staff but they didn't listened. This was the worst experience i ever had in rajdhani. The catering staff intentionally doing this to sell out the same to others.
