My Freenom account got banned?

Hello, so recently my Freenom account got banned letting me with blank domains. And that only was because i've used too many daphne.ns.cloudfare.com & devin.ns.cloudfare.com as nameservers.

Now, so i contacted Freenom support and nothing, they didn't reply! I think that if you wan't to be a formal company at least reply to my emails and fix your account revision & account ban algorithm!

Well, so just tell you that most of my projects are down because the domains are gone.
