According to my experience, often first comes an automatic response with already known solutions. If these do not help, you should answer so that a human is added. Even in the free plan I always had quite fast answers. If you have already done this you can just post the ticket ID. Maybe @cloonan can then look at why you didnt get an answer yet.
I have seen a lot of post lately that Cloudflare sites or services in Russia are not working properly. Unfortunately, the responsible people in Russia don’t seem to care that a block of a whole IP or a whole IP range does not only block the affected site but many services at once when a big provider like Cloudflare is behind it.
