Incompetence

Ordered 2 textbooks on Thursday afternoon, according to online confirmation it takes 3 days to receive via courier. I called to follow up as to where my package is and was advised I would receive it by end of day (this is the 4th day) I received an email confirmation with parcel tracking number, I call the courier company only to find out that my tracking number from van Schaik is for another customer situated in Nigel. I called van schaik back only to find out my order was mixed up with someone else, the books were delivered to the person in Nigel and I would have to wait for the courier company to collect the books from the incorrect recipient and then deliver to me. Worst experience ever and I am I frequent purchaser on online shopping sites. I have assignments due and there is no action plan given that will benefit me as a consumer. I have to wait as if it was MY fault that someone dispatched my books with the incorrect waybill. Why can't by textbooks be sent to me again...correctly this time and Van schaik can sort out their mess up with the customer that received the incorrect books??? Further more if I never contacted the courier company no one at Van Schaik would know about the mix up.
