BRAND NEW PHONE OUT THE BOX DAMAGED. NO UPDATE

i bought a brand new iphone 6 on contract online. it got delivered on 21/7/15. I realised there was a signal problem.i took it to the westwood mall Telkom branch on the 26/07/15 (Under 7 days). After checking the phone he tells me he cant do nothing. i must take it to the istore. WHY MUST I TAKE A BRAND NEW PHONE TO AN ISTORE WHICH IS INDEPENDENT OF TELKOM TO FIX A PHONE THAT CAME WITH A FACTORY FAULT. He says i can book it iin but it takes 3 weeks. I left there to go to the pavillion branch. PLEASE NOT THERE WAS NO MANAGER IN BOTH STORES. They say they cannot do anything even though it is under 7 days. After back and forth i go with the only option but to book it in. AGAIN i get no response the next day. i did get a response only after i complained on twitter on the 27/7/15. Thier reply was \ YOUR PHONE IS STILL WTH THE REPAIRS TEAM. IT WAS RECEIVED ON THE 26TH."today is the 31/7/15 and i get a text from telkom saying \""YOUR PHONE HAS BEEN ALLOCATED O A REPAIR CENTRE FOR REPAIRS. WE WILL CONTACT YOU WITH UPDATES\""<br> <br> FIRSTLY - why are they sending me the same update after a week.<br> SECONDLY- why am i waiting for a OUT OF THE BOX phone to be repairesd.<br> <br> I WANT A REPLACEMENT!"""
