I'm still waiting for my end-of-course trip money back.
They say absolutely nothing. What little seriousness.
One week after making the reservation payment, the first week of February 2020, my daughter told the tutor that she could not go on the trip, to which the tutor informed her that there was no problem with the return of the money.
Today November 15, 2020 I am still waiting for my money back.
And they also do not provide a solution.
