Google Analytics - Adding More Than 25 New Accounts

I have more than 25 Google Analytics accounts for which I'm an administrator, built up over many years of working with various clients. I have others for which I'm merely a User, rather than an administrator. I wanted to set up a new account today, for the first time in some months. Google won't let me. It says that I must "reach out to my Google Analytics support contact".

I don't have a Google Analytics support contact. I've never knowingly had an email or phone call or letter from Google Analytics telling me who my support contact is or how to contact the team. I don't interact with the Google Analytics team other than infrequently through the Google Analytics Help Forum and the Analytics API Help Forum (where I'm a lurker rather than a contributor).

So, how does one go about adding a new account, when Google prevents you, and gives you a completely useless diagnostic error message. Why is it completely useless? Because not only do I not have a Google Analytics support contact, the Google Analytics Help system doesn't cover this problem and the Help forum is a user to user help forum. It really isn't appropriate to go broadcasting an individual users problems' with the service. But there is no private route visible. So you either have to announce your incompetence in public, or forget about resolving the issue. Neither of these is appropriate for a well designed customer service interface with the business.
