Your name and contact details, the order or account number, dates, a short factual account, what you want, a deadline, and a list of the copies you enclose.

Frequently asked questions
Should I send it by email or post?
Either works; email is quicker, and a letter by recorded or tracked post gives you proof of delivery if the dispute goes further.
What if they do not reply?
Most countries have a free consumer advice service, an ombudsman, or an alternative dispute resolution scheme; for card payments, ask your bank about a chargeback.
How firm should I be?
Be polite and factual: describe the problem, say what you want, and give a deadline. Anger makes it easier to dismiss.
