I am facing the same issue. My multiple domains subscription and plan changed automatically. For that I have raised support ticket 3297450 but no response from support team for last 14 days.
Can I get support here to escalate this ticket 3297450 internally in Cloudflare?
I merged your duplicate tickets into 3297450 and will again flag for my colleagues in Support. Please keep the conversation in 3297450, no more tickets are necessary, that just slows the process.
I can see our billing team has made the necessary adjustments to your account to correct this issue. I apologize for any inconvenience this issue has caused. The case is now resolved, but do let us know if you need anything further.
