Checkout error "We're unable to place your order" — can't purchase after free trial, every payment method fails

Hi, I'm trying to purchase a paid plan after our free trial ended, but every checkout attempt fails with the error: "We're unable to place your order at this time. Please try again. If the problem continues, contact support."

I've already ruled out everything on my end:

• Payment method — I've tried a valid card directly and also PayPal; both fail, and the card provider shows no declined charge or alert.
• Billing address — entered correctly to match the card's country; still fails.
• No outstanding balance — we were on a free trial with no prior payment on this account.
• Not a browser issue — it persists in incognito and across multiple browsers.

I also can't reach Support to resolve it: opening a case logs me out of my account before I can submit anything, and live chat tells me that because I'm on a trial (not a paid plan) I can't be connected to an agent. Sales confirmed they can't access billing/checkout systems and sent me back to Support, so I'm stuck in a loop.

Since this appears to be a checkout error on Docusign's side, could a moderator please pick this up and escalate it internally? I'm happy to share my full name, account number, and account email by private message. This is blocking us and I'd really appreciate getting it resolved soon. Thanks.
