A consumer complaint is a formal expression of dissatisfaction or disappointment about a product, service, or overall experience with a company or organization. Consumers file complaints to voice their concerns, seek a resolution to a problem, or make a suggestion for improvement.
In general, consumers file complaints when they feel they have been wronged or treated unfairly. Complaints can arise from a variety of issues, such as defective products, poor customer service, billing errors, misleading advertising, or a breach of contract.
