Dissapointed first time bookabook customer

Worst experience ever. Firstly they send me and email and text apologizing for the late delivery then to make matters worse when the book finally arrives on a 6/3/19, it's the wrong book. I emailed them countless times notifying them of my problem and the fact that my first assignment is due on the 8/3/19 so they should refund me so that I buy a new text book instead cause the option of renting is now becoming an inconvenience to me. The only reply they sent to me on 7/3/19 was Good day, takealot will exchange your book... I asked for a refund
