Step-by-step explanation:
Claim (or complaint) letters fall into two categories: routine claims and arguable claims. This statement is true. Routine claims are those that are straightforward and easy to resolve, such as a request for a refund or a replacement of a defective product. Arguable claims, on the other hand, are those that involve a dispute or disagreement, such as a complaint about poor service or a faulty product. These types of claims often require more evidence and persuasive arguments to support.
