National City Bank - PNC Bank Posted transactions from largest to smallest regardless of transaction date, or post date then charged 2000 in fees on fees. Internet

I have only been with PNC for three months, and have been charged an insane amount of overdraft fees. Some of which where overdraft fees for their overdraft fees. I am done, they suck, I am suing. This all started when they posted my tuition payment before my book purchase. Though the book purchase was three days before the tuition payment. After my tution went through I checked the balance and noticed that the books had not posted. I deposited cash that day, it posted online, but the next day the cash deposite post was removed and the books had cleared. WTF? Then I was charged overdrafts ontop of overdrafts. I called to logically reason with PNC, I offered to pay what I thought was the none predatory fees. They disagreed, now I offer to pay nothing.
