College cancelled admission mid session wrongfully

My college cheated me. First, they gave admission in MBA to my daughter in 2016 .we clearly asked this institution, our mark score is this much, so is it applicable they clearly said it's OK . You can take admission.we have everything receipt and all. They kept our original certificates and money. After few months they said your percentage is not up to MBA graduate so then we asked it's almost one year complete you are informing now then we can't do anything. Then they said we have PGDM option and you will eligible from 2016 , go for this you will get same certification we agreed till now it's 2018 they are not responding anything we are just trying . My daughter lost two year They took money ,certificate. Now, what to do?
