Send a complaint letter online
Type your complaint, attach receipts or supporting documents, and we mail it as a formal letter through USPS. A mailed complaint creates a paper trail that email and chat support do not.
How it works
Four steps. Most letters take under two minutes from sign-in to mailed.
- 1
Write your complaint
State the facts in date order. Include order numbers, account numbers, and what you want done to resolve it.
- 2
Attach supporting documents
Receipts, screenshots, prior emails, photos. Up to five attachments can be mailed with the letter.
- 3
Enter the recipient address
Address it to the company's headquarters, the named executive, the regulator, or the state Attorney General's consumer protection office.
- 4
We mail within 24 hours

Frequently asked questions
Why mail a complaint when I can email?
Mailed complaints create a stronger paper trail and tend to receive higher-priority handling at most companies. They route through formal complaint channels and executive offices rather than front-line support queues. Use mail when phone and email have not worked.
Who should I address it to?
Address it to the most senior person you can reasonably name — head of customer experience, country manager, or CEO at the headquarters address. For regulators, address it to the published intake address.
What should I include?
A short factual narrative in date order, the harm caused, what you have already tried, and a specific remedy you want (refund, replacement, written response by a specific date). Attach supporting documents.
Are written complaints required for some regulators?
Some agencies (and most state Attorneys General) accept complaints by mail or online form. Some require specific intake forms — upload the completed form as a PDF and we mail it.
Will I have proof I sent it?
Yes. You receive a dated email confirmation, and the order page records the mailing date. The exact PDF that was printed is downloadable.
