Cloudflare is already activated

I tired to setup my domain with cloudflare on site ground hosting after transferring from A2 Hosting and I get this error"

Cloudflare is already activated for this domain under a different account.

I’ve looked in A2 hosting and can’t see anything about cloud flare setup I’m sure I only set it up in Site ground.

Site ground sent me here to get support can anyone please help?

How can I open a support ticket I could not that area it’s not very clear in the support area?

Open a ticket. Since that domain isn’t in your account, pick some other option for choosing the affected domain in the ticket process. Support will figure it out.
