A Company who don't care at all

On the 10th of March I ordered a text book my daughter needs for university. 7 days later i receive a email, sorry dont have the book anymore and got told order being cancelled. On the 13th of April after having to threaten them with you guys I got told I can cash my money out. I send an email requesting to explain to me how as I cannot get it done. No response to my question. Then I saw they got the book again but at R250 more as it is the latest ediditon. I then decided as I cannot get my money back and because i cant afford just to spend money left right and center to order the book. Trying to pay via EFT turned out to be a nightmare. as They on Standard bank preloaded as [URL Removed] and not com. And scare to loose my money I emailed and asked if this is correct. I received a answer the next day to say continue it is correct. i paid and send them POP. Yet the next two days I kept getting reminders to pay. i then send it off again and got a response that It will take 48 hours to clear. less than 24 hours later my order got cancelled, and i got told my refund will show soon. Now the book is once again not availble and my child is going into exams without a book.
