I was thinking exactly the same thing. The child has zero relevance in this complaint / story. I'd expect a bit better treatment and solutions for a Platinum and Gold member, but half the plane has a child, or multiples of them.

I've fortunately never booked a ticket with QR directly before (yet) so don't have to deal with the incompetence, but have flown them many times on other airlines' tickets. I can certainly see they have little empowerment at the transfer desks in DOH, but thankfully I've never been in a dire situation there. I can also definitely see the decline in service onboard but it's still pretty darn good most of the time. But this OP's issue seems to have stemmed from the flight change, and sure someone is to blame for not fixing it sooner, but no one is going to take ownership for that at QR.

Having said that, I can definitely feel the frustration of not getting decent and expedient service when the issue was discovered. After many years of being either AA EXP or UA 1K, I have been spoiled by the level of service their dedicated call centers provide when something actually does go wrong. They are truly empowered to make stuff happen and something I'd also expect as a QR Platinum on a QR ticket... it's a real shame they don't have a better Platinum service center.

OP you have a valid complaint for certain, but I'd recommend completely remove the child from the picture in the complaint as it has zero relevance in what transpired. Sure it makes travel more stressful but that's a choice you made and shouldn't / doesn't affect recovery when something goes wrong. Also as someone else mentioned, cut the text down significantly, stick to the facts and leave the emotion out, you're more likely to get the desired results.
