Write to them via their User Interface, worked for me the past week.
Go to their website and submit a ticket: https://njal.la/support/
I just checked the site and didn't see any issues with my account or services.
Who uses twitter for support messages anyway?
My website got back yesterday and for the fuckup, they extended my server for 4 weeks. It was down for 2 weeks, so 2 weeks extra.
I'm grateful, but .....
