I am absolutely astounded that after paying them all that cash they are trying to fleece people out of more.
This is the kind of thing fraudsters do. Once they think they have someone gullible enough, they squeeze every last penny out of them by making them think there is only one last obsticle to pay for.
The whole integrated thing seems to me to be based upon getting a good report from the school. This means as said above that people are scared of creating a fuss if they feel they are being ripped off because they might not get that good report at the end.
