Set up a bug report template

To be fair that was incredibly unprofessional of you. You yourself have no idea if it fixes or introduced new bugs. That in itself should have been enough for you to not push those changes. If she has the tendency to ignore warnings then you can avoid all of it by not doing changes and assume the issue is potentially fixed unless you know for certain it's fixed. Imagine if products you used has developers doing this. Keep in mind I'm not saying she right, but you aren't either.

Honestly, they are not wrong, but they ARE being a total asshat.

They are wrong in that they are just being disrespectful, but it kinda is our job to know if we have solved an issue or QAs job to assure it's fixed. We can't always rely on the customers.

Maybe the guy just had a hell of a day because of the mentioned issue thus causing his reply to be like so. All in all, I think he's right but not the way he delivered it.

Just make sure your progressing with your career skills, keep learning. Don't let big companies and their horrible standards ruin you. The pay may be good but in the future when they inevitably decide your no good for them anymore you'll have to be up to par on skills with others. It's very easy to get comfortable and go stale in those big ones, although I cannot say for all of them. Just keep that in mind and take care!

It's to log the development work, and to know the shit quality they did by linking the parent task, that dev better step up his game and do things correctly

Hats off to them for trying and asking for help, better than those that wait until the sprints ending

Bugfix = that thing that you merged that wasn't breaks things but nobody noticed until someone complained about it
