I sent an application and cheque for the A2 Delf, based on the dates they published for the test. I received a confirmation that they received my application and cashed my cheque, but then they changed the exam dates than what was published / what I was available for, so I could no longer go. They agreed to refund me, since it was their change, not mine.
It s been a couple months and lots of emails and still no money back. It s not cool that they publish dates, you pay, and then they change the dates.

They also did not follow data protection laws, and used the to: field on multiple emails to large groups of people so that all email addresses were visible. This is a great example of their organisational skills and makes one wonder how they treat confidentiality.

The contact with the people working there has left much to be desired - most had no idea what the processes were and gave conflicting information. It gave the impression of gross incompetence.
