Adding Voice line keeps failing — need a manual/back-office fix

I need help getting a Voice line added to my account. Every attempt has failed and I’ve already spent a lot of time on this.
I go through the full add-a-line flow — choose the plan, get assigned a new number, approve the pricing — and at the final step the order errors out and doesn’t complete. This happens both online and when a phone rep tries to do it on their end.
I’ve already tried:
 • Multiple attempts online over different days
 • Different browsers and the app
 • Two phone reps, each of whom hit the same error on their side after I approved everything
At this point I don’t think anything in the standard self-serve or front-line phone flow is going to work — there appears to be something stuck on the account side that needs a manual fix or a back-office ticket. I’ve seen other threads where the forum team was able to resolve this kind of error.
Could someone from the team please reach out so I can get this pushed through? I’d like to avoid another multi-hour phone session that ends the same way.
Thanks.
