Economy service in PE CX714- resolution?

Hi all,

I hope I may not sound like a PITA here and would like to share my experience w fellow travelers and seek advice before my next flight.

I was initially thrilled with the PE service offered by CX from SIN-HKG-MEL and I just ended the first leg of my flight. However, below is the service that I have received and am not sure if I have been short-changed by CX and would definitely seek advice before pursing further with this matter.

There was NO amenity bag and NO welcome drink and neither was there any got tower or menu for supper.

Supper was just a packet of orange juice, pandan cake, kitkat and sandwich which I presume is the same for Y pax.

Crew was never seen thereafter and neither was there any round of drinks served prior to arrival etc.

Basically, it's board plane, the above food and that's it.

Am I being short changed by CX? Can I raise this issue to the in-charge here in HKG airport before my next flight departs in approx 19 hours?

What would you guys do?

Seems like it's an overbooked flight, departure was delayed due to late arrival and Y+ was initially 4 pax while checking a few hours before check-in but became full when I boarded e plane
