I've asked the support team to change the address on my last invoice to a changed address. After now 12 messages and still the support person don't understand, I want to escalate the case, but I donn't find a possibility to do it in the system.
I don't have an answer to your question, but I can direct you to a FAQ article on how to update your billing address.
