Say sorry in public when something has gone wrong

Help me write a calm, honest public statement after something went wrong.

What happened: [the facts as you know them]
Who was affected: [e.g. customers who ordered last weekend]
What people are saying: [paste a few comments]
What we're doing to put it right: [actions]
What we don't know yet: [be honest]
Any safety, legal or insurance side: [yes / no / not sure]

Ask me up to 4 short questions first. Wait for my answers.

Then:
1. A short public statement: say sorry plainly, what happened in brief, what we're doing, and how people can get in touch.
2. Three short replies for common comments: an angry customer, someone asking questions, and a supporter.
3. A private message for people directly affected.
4. A plan for the next 3 days: when to update, what to watch.
5. What not to say.

Plain and sincere, no excuses. If there's a safety, legal or insurance side, tell me to get advice before posting. UK English.
