Minecraft / Mojang new acc?

Se
3

I changed the e-mail address on my old mojang account and wanted to use the old one for a new one but this did not work. I waited 2 and a half hours but it still did not work so when can I get the e-mail address from the old acc again for a new use?

Already in advance thanks for the answers

ev

This is probably due to mojang otherwise just wait or take new email

But I can't / may not do an email so what can I do there and how long does Mojang support need to answer?

ev

How old are you?
