It won’t let me back into my account – Minecraft Review

So I got my phone taken away for a few months and when I got it back and tried to sign into my account it wouldn’t allow it. I’ve tried my email as well and it still wouldn’t work saying it wasn’t a valid email, but when I tried making a new account with that exact same email it wouldn’t let me. Can you please fix this?
