I'm currently having problems with my Minecraft account and have already written to support, but now I would like to speak to someone personally. Unfortunately I can't find a number. Can somebody help me?
Minecraft does not have telephone support.
There doesn't seem to be an official phone number for customer support.
Alternatively, you can use the contact form.

Then you should be able to imagine that there aren't any either.
The support will get in touch at some point. If you called there it wouldn't go any faster.
I just don't know if I will ever get an answer because my account has an email problem.
You can enter an alternative email address and the transaction ID. Then they can contact you there.
