How to change company name and address.

two issues I cannot seem to change.

My company address on the developer account is wrong and there is no option to change it. I have filled in the contact form a couple of times to request a change, but nothing happens, it's still my old address.

When I publish an app through TestFlight, it says it is from a different organization to mine, the organization that it says it's from was another developer account by a customer that I was invited into, but I have removed myself from that. Yet my apps still say it's from that other organization. Yet in my account there is absolutely no reference to that other organization anywhere anymore. So I I'm really confused how to change it to my organization. I can't publish any apps on the App Store until this changes.
