The whole point of bambu was that it was a 3d printer for people who didn't want to tinker.
The people on this sub assume everyone who buys products do a ton of research on the companies making those products instead of just watching a couple reviews.
Most people are not as informed as those that appear in a dedicated 3d printing sub.
I dont have much advice, but I will say this: there is nothing wrong with being upset you weren't given a fair shot.
How you handle that or what your follow up is, I don't know, but you being upset is absolutely a normal response to this.
