Shocking service and still waiting for good to be delivered after payment 4 months ago with no communication from owner as to whereabouts of my order.

I ordered educational books from Lauryan Ritzlmeyer who owns Edukits. There was a problem with her website payment system so she sent me details to pay via EFt. She said she would send me a detailed invoice and that the books woild be on their way soon. Once i made payment, she stopped replying to emails abdphone calls for about three weeks. Then eventually got hold of her and there was one excuse after another about late delivery. Books stuck in customs..her email address then didnt work...then she crashed her computer. .then she lost my details apparently. I was told 3 weeks ago that she had the books and was to courier them next few days. When they didnt arrive i phoned her and she sounded surprised and said that the courier had fetched them. I phoned the courier company that she uses and they said they had not collected a package from edukits that week. Since then, she does not answer my calls or messages or facebook messages. Since doing some asking around, I found out she has had similar excuses for other customers who waited months for delivery or ended up cancelling their orders. My concern is that she makes no effort whatsoever from her side to update me on he whereabouts of our books. Any contact I managed to have was of my initiative.
