So my account got automatically migrated in April, and since that time I cannot log into Minecraft. Either I try to log in with my e-mail or with my username, it doesn't work. If I do it in Minecraft Launcher, it says it's migrated, if I do it on the website with my username, it says there's no such username. I'm still mailbombing the Mojanh Help Center, but still no answer. I tried everything, resetting my password, etc., but my e-mail address which is registered for my MC Account is very old and buggy, I don't recieve any mails from Mojang. I really have no idea what to do ,can someone help me?
