Open Help and support, under Administration, General section. Anyone in your workspace can write there, but the menu entry is only visible to administrators: a blocked person who does not administer goes through one of them.
Your request is sent with the context of your workspace — the plan, the subscription state, the screen you are writing from — so that the first answer is not a question. Nothing about your own customers is attached.
MAYA does not answer a product help request itself: the publisher answers, and the reply reaches you by email. Your request RINGS at the publisher, because a blocked customer is urgent.
You can send several requests in a row, within a reasonable limit per hour: it is the publisher's queue that is protected, not your voice.
To know whether an outage is on your side or the service's, open the status page, which is public and needs no login. It gives the state per FAMILY — conversations, messaging, publications, automations, documents, data — and never says all is well without having measured it.
