Regarding bad customer service, many people choose to give verbal feedback. They are very direct in showing their unhappiness, either immediately or by making a phone call. Basically, they explain to the staff what made them upset and the reasons for their dissatisfaction. It's not only about expressing their feelings. They often also suggest how the service could improve. This indicates that they're not only complaining but also want to see positive changes.

When there's bad customer service, many people now choose to contact the company online. It's usual to see them using a company's website or email for customer service. This way is easy and keeps a record of the complaint. Also, people often post their issues on social media and tag the company. This public way of doing it can get quicker and more careful responses from companies, and it also lets others know about the service quality.
