Has anybody ever had any success on this query from Apple? I have seen several threads about this topic, but not one solution yet. What does Apple prefer - that we rather create fake Apple ID's with dummy e-mail addresses, so that we can use those usernames? (Which is what this address is - the e-mail address will never be checked by me, but I used it since I did not like my previous username, and cannot change it...).
Also, can the posters please check the answers before posting: There is no way to delete an existing Support community account without deleting an Apple ID, and you cannot create a different user account on the same Apple ID. The answer os not helpful, similar to this post which only refers to the global site without any help.
