Final answer:
The correct approach to handling complaints is being professional and courteous, not loud and rude. Proper business communication is key to resolving issues effectively.
Step-by-step explanation:
When dealing with complaints, it is crucial to remain professional and courteous. The statement suggesting that one should be loud, direct, and rude is false. Proper business communication dictates that one must be clear, concise, and to the point, ensuring a polite and solution-focused interaction. Using text language is not considered proper in business contexts, and one must always strive to use complete words and correct grammar. Being professional not only helps in resolving the complaint effectively but also maintains the reputation of the business and ensures customer satisfaction.
