Interesting. I looked into the subject out of curiosity. So this is what all this fuzz is about, the Persona registration services. I can shine some light on this matter and provide some useful information.
To make it short, you are barking at the wrong tree, @please-save-my-earth . The Support Team was not lying or short-cutting, when they told you their hands are tied. It’s a third-party service, who is well known for having a lot of issues. This general problem is well known and dates back at least 2 years now. You are not the first person, who encounters its “moody nature of the registration lottery”.
I skimmed through your previous posts. You have mentioned that you already have your main seat professionally in another AI laboratory and wanted to register this one for your private use cases. I will boldly assume that you have not checked the terms of the third-party company in order to find out, why your registration failed, when it has succeeded elsewhere before. Sometimes life is “unfair” and not an all you can eat buffet.
Quite frankly? You are a lucky one. I have seen countless people gotten only one-time chance to register, a system hiccup sabotaging it and no chance of ever registering at all systemically. Simply softblocked. 
I also boldly will assume that you have not carefully read OpenAI’s documentation. Otherwise you would have noticed the disclaimer that it is not guaranteed to work for everybody at any condition. OpenAI does not make the rules.
Is it a wonkey system? Oh absolutely. Is it OpenAI’s fault? Nope. It’s young and buggy. We joke about this service in my region. Does OpenAI have to comply to certain laws and requirements around the globe? You can bet on this.
So. You might wanna have a look into how many seats you even can have in such a hot field of yours. Such services exist because of identity theft and similar problems in the past.
With a little more research and a little more critical thinking you can figure out and even solve a lot on your own. Don’t expect everyone else to jump as soon as there is a problem, which needs a bit more effort to solve. There is no use in getting angry, because people do not match your expectations of an easy immediate fix. You might not like this answer, but that’s the reality.
Have a good start into the weekend everyone.
