Whale Coast mall, Incredible Connection DISSAPOINTMENT

I bought a X BOX ONE A WEEK AGO. FROM THE MANAGER HIMSELF WHO ASSISTED ME, WHALE COAST MALL.. I WAS TOLD THAT IT WOULD BE DELIVERED IN TWO DAYS TIME. GUARANTEED AS HE SAID AS A BACK UP THE STORE WILL ALSO REQUEST A ADDITIONAL MACHINE SHOULD FEDEX NOT BE ON TIME. IT HAS BEEN 7 DAYS, AND NOE THEY SAY FEDEX DO NOT WORK ON WEEKENDS???
