False Advertising and Terrible Customer Service

I ordered from Zando on the 30th of May. I received an email from them on Tuesday, 5 June apologizing for the delay, they also supp**** me with a R100 voucher. I received another email on Thursday 7 June, saying that my order has been dispatched. Today is the 15th and still no order. I phoned twice with no success. I just received a message from Zando saying that Dawnwing couriers lost my order in transit and that I will receive my order before 17:00 today. This is not good enough, someone needs too be held liable and fair compensation must be given!!! I could have used my money elsewhere but unfortunately chose Zando, it will definitely be the last time! There is an obvious problem.....why aren't you advertising that on your website? Seriously guys, you are going to loose a lot of customers.
