Honestly this is pretty much it. Sometimes you have to be pretty aggressive to get companies to do the thing you need; they will take advantage of the social friction required to keep you in predatory arrangements. They literally design it to be frustrating so you’ll give up. Like you, I try to make it clear to the person I’m speaking with I have no problem with them just the business. But if the corporations require me to get mad to do the right thing I will get mad.
