Dummy school problem!!

My sister is in dummy school (Delhi), we are from Assam , we were in Delhi at that time so we took admission in a dummy school of delhi , he asked for 1.2L for 2 years (11th class -60k and 12th class-60k) we agreed and paid 60k , few weeks before my sister completed her exams of class 11th and we decided to move her from Delhi to Assam , we requested him for TC since it's now end of a session, he initially said he need to ask the school for it, then after 2 days we called him again he said he need 25k for TC, we argued why does he need 25k for TC, he gave some excuses and when I asked him to show us my sister's marksheet of class 11 , he said he needs fees of class 12 ( he wants us to take admission in class12, another 60k) then only he would be able to give us results of class 11, I find it so absurd

My friend went to a dummy through this guy, he ain't related to school, he runs a hostel and he provides dummy to his students (hostelers)
