Infibeam
Books not received

I preordered a set of books from Infibeam.com a month before the release date. On the date of release i got a mail from them that the item has been dispatched but i dint receive the books. I called infibeam to check about it. They told me that someone will get back to me in 24 hours. But instead i got a mail that my order has been cancelled. I called again 4 times to check about it but everytime i am told to be patient and someone will get back to me. How convenient of them to cancel the order without asking me or they dint bother to inform me if they were out of stock. my order id is- 8202327
