How to get the best service following a worm in my food?

On my flight from GRU to IAD there was an inch long knobby worm in my chicken dish. The Flight attendants didn’t respond to either my or my wife’s calls, we had to wait to grab one after about ten minutes and the dinner service was ending.

They were nice enough about it, but my wife literally went to throw up and didn’t touch her breakfast either. We flew Premium Plus so we paid for a great experience and had a pretty nasty one.

what should I do next? They gave 10k miles to my MileagePlus account but that’s like $100 from a $1600 ticket. With the cost of gas going up too, those miles are likely going to be worth even less.

we have pictures but I chose not to post them.
