You described quite a positive picture of the school and you became disappointed only recently, in a way understandable, but are you reasonable? There is a situation with ALL schools in Spain and beyond, a terrible situation in half of the world already and expanding, unlike anything we have ever seen in our life times. You have just been utterly unlucky that this happened just when you were in your first month. If you are still in the country under lock-down, use the ocean of time at hand to study the language of the country. Would have been best to start right away when you initially arrived, but hey, better late than never. Once all of this is over it will be a tremendous asset when you continue to live and work there. If you have left, good luck there, but don't kick back at the school that has suffered the same shock and fate as so many others.
