Don't Rent Textbooks from Here

“I ordered two textbook rentals on Sunday and paid for express shipping. I was told books would arrive by Thursday. I saw that the tracking info stated books would arrive by Saturday. I contacted customer service Tuesday and was told books should arrive Thursday. Friday night, I called customer service to find out where my books were. The customer rep said that she would refund my money. I said that I don't want a refund, I want my books. She said my account would be credited and if I get the books, just send them back. No help whatsoever. Basically I got the big "Screw You!!!" I have a paper due tomorrow, and no text book.”
