Do Not Upgrade. (Code: 1315)

Hello i have an error while trying to add an account to cloudflare it says “Refer to for assistance. The zone you are trying to upgrade is marked as Do Not Upgrade. (Code: 1315)”
the problem is i have created a ticket in Billing/Upgrades section 3 days ago and so far there is no reply from them so far
ticket id #3257208
should i subscribe in paid cloudflare plan so i can get a reply from them? as i’m currently on the free plan
