I HAVE BEEN QUERYING THIS SINCE 03 JUNE 2015 WITH NO JOY BEING SENT FROM THE GLEN TO FOURWAYS, TODAY THEY STATE THEY HAVE NOT RECEIVED MY DEVICE FROM THE GLEN, THIS DEVICE IS NOT GOING ACROSS THE COUNTRY I DONT UNDERSTAND THE DELAY OR IS IT JUST SOMEONE'S INCOMPETENCE, I WAS TOLD THE TURN AROUND TIME FOR A REPAIR IN 7-10 WORKING DAYS ITS ALREADY BEEN 4 DAYS AND ABSOLUTELY NOTHING DONE!!! I WAS TOLD BY THE TECHNICIAN THAT WITH APPLE THEY DONT REPAIR THE DEVICES THEY SWOP IT WITH A REFURBISHED ONE, HOW CAN I GET A REFURBISHED SECOND HAND DEVICE WHEN MY PHONE WAS PRACTICALLY BRAND NEW (3WEEKS OLD) FOR A FAULT THAT IS A FAULTY DEVICE, TOTALLY UNACCEPTABLE!!!
