Answering the actual question seems not a high priority
The older I get the less I want to deal with companies that act like primadonnas and the technologies they make. This is also why I don’t do phone apps: your market access is 100% controlled by two companies that can wipe out your business overnight.
Imagine having to work with these people professionally. With real money involved. While probably not as high risk as mobile development, their customer representatives seem like real primadonnas. You’ll be happier without these people in your life.
I’m actually fully in favor of empowering customer-facing representatives to put reasonable limits on responding to customer abuse.
It should not be the job of a forum moderator to take abuse. Warning them about the rules of the forum and then enforcing the rules is forum management 101. It’s getting silly that people are attacking this person specifically for just doing their job.
Typical phone CSR boilover from covid days. Most places I call these days have a message saying that they will hang up on you if you act pissy.
