hey there I ' m sorry you had to deal with such non professional people , normally them hanging up on you means the person you need to talk to you isn ' t even in his office typical . Did you try calling the ministry of higher education , international cooperation department tel 66 tel 772 ? I dealt with them before and they may be slightly better . Anyways , it ' s always better when you go to the university on the spot . you do know that the university is just the head department of the all Mounastir schools right ? ? not the school itself so maybe you can as well google the school you ' re heading to , and give them a call . Always keep calling and messagibg till you get an answer . the key to life in Tunisia is patience lots of it unfortunatly .
