How to figure out which account owns a Deployment?

I have my Deployment ID, but I set this particular machine up 4 years ago. The account was under the old FreePBX login, but now I’m not sure if it got moved or what. Is this something to direct to Sangoma Sales? I need to purchase EPM, and just need to login to complete the purchase.

Open a support ticket (link above) of type “Customer Service & Billing” with the deployment number.
