I'm sorry to hear that the document that you're trying to upload for the name change process is not being accepted. In addition to the file size and type requirements, I've also heard that if the file name has a string of numbers in it, it may cause an issue. Please try renaming the document if that is the case.
If you still need assistance, please try calling as @sharpiemarker suggested. However, for best results, please use the automated system as designed rather than jumping immediately to asking for an agent. Telling the automated system what you specifically need ensures that you are routed to the correct team, whereas asking for a live agent may cause two separate wait times while you wait for someone to answer your initial call and then route you to a different team.
I hope this is resolved quickly for you!
