Phoenix University is Unethical! Phoenix University, Axia College, Apollo Group Phoenix University are Unethical Scammers! Beware! Phoenix , Arizona

This place is a rip off!  I was doing very well. I had maintaied a 3.0 average for the first year of attending.  Then, out of nowhere, Phoenix deposited almost 3,000 of my student loan money into my account. I went to the website to check my Pheonix Account.  There was a reciept fo the deposit which said "Refund".  I printed it and had it sent to my e-mail.  This was a blessing because I am a single mother and my son and I had been going through hard times.  Two weeks later I get a call saying it was a mistake, that it wasn't a refund, it was my tuition for my upcoming classes.  The money was nearly gone by then.  I explained the situation and sent them a copy of the reciept they had given me.   The say "so what"  " You should have known."  I pointed out that they  had never deposited money into my account with a reciept for "refund" in the past, and "how would I know".  I asked if there was something that could be done. They said "Pay out of pocket."  Like I said, I'm a single mother and can't do that.  I had to quit school and now face paying back $18000 for the year I attended.  I feel sick to my stomach.  These people are very unethical.  If an attorney is reading this:  They changed the information on my account after I complained, (because they know they made a mistake) but I sitll have the reciept they sent me and it is an Abdobe "unchangeable" file.  I would love to sue them!
