For money questions on an account that already exists
Narrow on purpose: an invoice, a payment method on file, or a question about a plan already running — money questions specifically. If the question isn't actually about money, it belongs at support instead. A billing inbox that quietly absorbs every account question stops being useful for the thing it exists to handle well.

None of the three is ranked above the others, and a message doesn't need to fit neatly into exactly one — a failed payment method that's also raising a plan question is still one message, not two.
The test is simple: if the actual question is “why does this charge look like this” or “what does my plan include,” it's billing. If it's anything else — a setting behaving oddly, a login problem, how a feature works — it's support wearing a billing-shaped question, even where money is mentioned somewhere in it.
It also isn't where a caller's own payment gets handled — a diner's card is a completely different mechanism from anything on this page. Payment security covers how that works and why a card number is never meant to reach a Dohos system. And it isn't a security channel in a billing coat: a charge that looks suspicious rather than merely wrong — one that raises a real question about account access — is closer to security's territory. The test: “this number looks wrong” versus “something about how this happened looks wrong.”
A genuine question about what a different plan would cost is usually better answered by pricing directly — the plans and the per-minute mechanism are worked out there in detail, and the estimate sizes a real number against real inputs. This page is right once the question is specific to what's already on the account.
Can I change plans through this form?
The real path is honest, not a self-service toggle: a message here starts a request, and a person reviews and makes the actual change — no button swaps a plan instantly, in either direction. A change that's actually decided, not just a question about one, still starts here.
Can Dohos freeze or hold funds in a billing dispute?
No — the restaurant is the merchant of record on its own payment account, and Dohos isn't in a position to freeze or delay a restaurant's own payouts outside a real, governed process. Raising a dispute doesn't put your funds at risk of being held back.
Does writing in affect the account's standing?
No — asking about an invoice or a charge is an ordinary, expected use of this page. A restaurant that writes in often because it reviews its invoices carefully isn't treated differently from one that rarely does.
What if the charge is for a caller's order, not the account?
A different mechanism entirely — a caller's payment runs through the restaurant's own transaction, not through anything Dohos bills the restaurant for. Naming that distinction in the message avoids a reply that has to ask which kind of charge is meant.
Can I get a copy of a past invoice?
Yes — naming the specific period is enough; there's no separate request process beyond writing in and saying which one.
What if more than one person handles billing?
That's fine — this page doesn't require one specific named sender, only someone with real, current authority to ask about the account's charges.
For an existing account with a specific, live symptom, the help section often gets to a fix faster than a message and a reply — it walks the exact screens, step by step.
