I just went to Help on the web page, asked some generic question in their automated help and then answered No that the answer didn't help me. That got me to the Customer Care section where I explained in detail what my situation was as well as league id's, team id's, user id's, etc.
They won't let you go over the max of 4 teams per id but they'll let you swap two teams between the id's.
