3 day orders actually take 3 weeks!!!! :(***/GO.

I places an order on their online store on the 2nd March. The confirmation email I received from them said that I would receive the goods in 3 working days. On the 8th I sent them an email requesting an update, I received a response on the 11th saying I should have feedback within 48hrs. I just want to know where my order is!!! This is completely unprofessional and uncalled for. I need the goods last weekend already, and I was counting on having them since the promise is "3 working days". This is just wrong and *********!!!!
