Ultimate Medical Academy UMA Overcharging, impossible to contact, horrible communication, lies, lieing  Internet

Ultimate Medical Academy and I agreed upon a total tuition cost of $17,000 and some change including books, supplies, and final exit/state testing. My graduation date was set to be July 12th of 2013. 

I am now finding out less than three months before graduation, I have been charged over $28,000 with no explanation. My graduation date is pushed back to July 21st and now August 3rd, also with no explanation as I haven't failed any courses. 

This school is out to rip people off, after much research on the internet, I am not the only one to have been ripped off. I wish I had done my research beforehand. Also they are impossible to contact. I have left over six messages with the financial aid department and cannot get a call back, yet somehow they find the time to send me threatening and harrassing emails. 

They have now threatened that until I pay off over $5800 I cannot receive my diploma, saying that is my outstanding bill, however, if you look at the paper work, my actual outstanding bill is over $8,000. So I decide to email them and I get told my outstanding bill is now $800. This doesn't make sense. 

They are out to take advantage of young people!!!!!
