Unfair Diagnosis

Where can I form a complaint about a service charge where :

Photos from the service documentation and the damage claimed have not been provided

I am not sure if the shared photo of the damage is a photo of the motherboard of the model: MacBook Pro (13-inch, 2020, Two Thunderbolt 3 ports)

I suspect unfair performance of the warranty service - a service technician is also a human being and can make mistake.

You should have posted the photo directly since we are now looking at a photo of a photo with the laptop's glass distorting the image. The bluish spot looks like corrosion from liquid damage as best that I can tell. It is highly unlikely a tech would have caused that spot of corrosion I'm seeing.

Like @leroydouglas mentions you will need to take the issue up with the manager of the repair shop or with Apple support or perhaps Apple corporate.

All the appropriate contact links given above..

beyond that you can submit your Apple Feedback http://www.apple.com/feedback

That really does not matter since there is nothing we can do. You need to follow the advice already given.

Since we are all other end users here and are not allowed to open our devices, how would we know unless we happen to be authorized repair personnel who has worked on your specific model?
