Apple has the worst support in the world. They always have 2 options - "You can't enroll" (I see that I can't enroll), or they ignore you. You are the most technological company in the world, and you use an ancient payment service. What should take minutes, stretches out for months. You have thousands of professionals, but no one can look at the logs and say what the problem is. Why do you need support if it does nothing? You have Apple Pay, why we can't use it? Any small company can configure payments, but you can't!!
