Pro account suddenly downgraded

I just paid for a new Business Account and team. I tried to invite my colleague as an admin and switch my profile to an Unpaid Admin. Unfortunately, it didn’t work as expected. Now, all I see on my profile is the option to buy a new Business Plan subscription.

Why does nobody response on any channel? What kind of scam is this? I paid for nothing.
