Don't buy a e-book

I have bought an e-book from PNA and have already paid for it. However, the website told me that I could not download the e-book. After numorous enquiries I received the following email over and over again:<br> <br> <br> PNA digital order reprocessed<br> <br> <br> Dear Mrs. Alisha Esterhuizen.<br> You have placed an order for the following items that requires a download link. At the time this order was processed, a technical error occured and we where unable to send you the required download url.

My money is gone and I still do not have my book.
