Dealing with aggressive customers course

Deal with complaints and dissatisfaction more pleasantly in the future

A customer who feels not understood. A buyer who is dissatisfied with a product. People who find your telephone calls disturbing. Employees in commercial positions increasingly have to deal with aggressive customers. This aggression is often caused by frustration, fear and uncertainty. In addition, instrumental aggression can occur when a customer feels entitled to certain services, products or satisfaction. Especially if you have to say no, the fire can quickly flare up during such a conversation. Moreover, the disadvantage of telephone contact with a customer is that there is no body language. Therefore, the use of the voice and communication skills are essential for a calm and pleasant conversation.

How do you deal with resistance and aggression from customers? When acting professionally, the complainant's emotions are not bottled up and suppressed, but guided, timed properly and processed. In the training 'Dealing with Aggressive Clients' you practice with situations from daily practice. In this way you become more skilled in assessing and de-escalating difficult telephone conversations.


The two-day course 'Dealing with Aggressive Clients' teaches you how to act professionally in cases of verbal aggression. This is always conscious action, based on one's own choice. Perhaps with, but not controlled by emotions. In this training, together we make sure that you are stronger. What is needed for this?
  • insight into your own behaviour: a certain degree of self-control.
  • A good assessment of the situation. The way you assess a situation depends on your profession, the concrete situation you are in and your personality.
  • Various de-escalating interview techniques.
On both training days, we work with an actor to simulate realistic situations. By experimenting with these situations and determining the approach that best suits you and the situation, the theory of this course comes to life.

Target group

The course on Dealing with Aggressive Clients is intended for people whose job involves dealing with complaints or dissatisfaction and who would like to make this more pleasant. For example, helpdesk staff, employees of housing corporations, receptionists and telephone salespeople.

Working method

The exact content of the Coping with Aggressive Clients course depends on the participants' prior knowledge, practical experience and learning goals. You start with an individual intake interview in which you determine your personal learning goals. On this basis the final programme of the training will be determined.

At the end of the training, we draw up a plan for giving and receiving peer support (buddy support). This lowers the threshold for asking each other for help on the shop floor when necessary. Afterwards, we evaluate the training in an oral and written evaluation. Some time after the training, we contact you again to see how things are going in practice. Do you need extra support? If so, we will plan a time to discuss cases from your daily practice and go deeper.

"Excellent training

"Very nice school to learn a variety of training with dedicated experts."

"The training was given at a good pace and the participants were able to keep up. It was not a large group, so there was enough room for the individual. The material was in a logical order, so that by continuing the training you kept repeating the basics, which keeps them up."

"Very knowledgeable trainer with a broad knowledge of the subject. The facilities are excellent. The course day (7 hours) is just long enough to stay focused.

"Tailor-made training! From the intake, the training was adapted to our (my) wishes. The training fits nicely with the practice."
