Defective Product Complaint

Use this when a product you purchased turns out to be faulty, damaged, or unreliable and you need to put the complaint in writing. It works well when customer support has been slow, unclear, or simply has not fixed the issue, and you want a more formal record of the problem.

The design uses a clean complaint-letter format with a soft administrative header, clear sender and recipient blocks, and a product summary card that highlights the purchase details and requested resolution. It feels structured and serious, but still easy for a company complaints team to scan quickly.

Katalisx helps you turn a frustrating product issue into a complaint that looks organized and credible. If you need to request a replacement, refund, or repair in writing, this template gives you a clear starting point.
