What should I do if my Ed visa application appointment is canceled due to technical issues at the embassy?

Hi! 2 friends have been today at the Embassy in Viebtiane for applying for the Ed visa. The Embassy didn't allow them to enter as they have a crash in the system and all the appointments are cancelled. They are tryin to fix it but at this moment they don't let people come in. So my friends are going back to thailand and try to understand what to do with the school. Is this happening to any of you too? I have booked the appointment on 27th of march... and my letter expires on 28th. If you have update info on what's going on... thank you!
