Locked out and separated

Hello, I returned to playing classic WOW, when we got restricted from going out due to Covid19. My Son told me about Classic, and we both made accounts on Kromcrush server. Got to the contested territory areas and there was NO Alliance. The few there would not even fight back because they were so outnumbered. We wanted to transfer to a more balanced server and picked Earthfury. I transferred in the afternoon to check it out, and when my son wanted to transfer in the evening the server was locked. Your GM’s said they could do nothing! Can I migrate back now without waiting for 90-day cool-down? Can you help at all? Not feeling any love here! Thanks
