What happens to your complaint?

Once we have received the complaint, you will receive written confirmation within two weeks. The management is responsible for handling the complaint. You will receive a substantive response from our director Caroline van Blerkom as soon as possible (in any case within 2 weeks). If more time is needed to investigate your complaint, we will let you know. We will then also give you an indication of when we expect to be able to give a definitive answer. Of course, we will always treat your complaint confidentially. A complaint will be kept by us for 2 years.

Do you disagree with our decision?

Then you can appeal. You can let us know in writing. We will forward your notice of appeal to an independent third party. This is the Consumer Disputes Committee in The Hague. Lexicon Trainings is affiliated to this via NRTO. If they decide in your favor, we will follow their decision. We will then ensure that your complaint is dealt with.
