So much for Express Delivery

So i ordered online for the first time on thursday the 26th of November and opted for express delivery which would take up to 3 days, today i phone the store and find that nothing has been delivered yet i recieved a shipped notification on monday the 30th November But the employees dont even know the details to follow up with the courier i then found the couriers details and got bounced around from extention to extention and still no answers. Im actually disappointed with this service and as a fist time online buyer i definately wouldnt do it again.
