Did PIWIK delete my account without any warning?

I got from my vacation and noticed that on August 20th Google Analytics stopped collecting my traffic data.
I visited my website and all the functions implemented via PIWIK Tag Manager are not loading.
I tried to log in to my PIWIK account, but when I’m trying to access my *.piwik.pro subdomain, I’m getting “Error 404 Resource not found” message.
(Happy to share all the details in a PM, but not sure whom should I message.)

I didn’t receive any message about my account going to be deleted, or anything like that.

Please help!

Hello @Konrad_C - can you send me more details?
