Ridiculous service from autopage

Hi. I got my new contract phone on Monday 10th August 2015... And was very happy with the service i received from the branch. But on Thursday the 13th August 2015, my handset developed a dead spot on the screen. I work in delmas so it is a big mission to get back to east rand mall to sort the phone out. I had a chance on monday morning to do so, so i contacted the branch and informed them of the problem to which i got the reply, that it is out of the 7 day swap out period... 7 Days from Monday is the following monday so i dont know why i was told it was out of the swap out period? I have been a loyal customer to autopage for countless years and this is the first time i have ever had a complaint about it. I then get offered a refurbished handset??? How is that at all fair?? When i contacted the branch to sort the problem out it was on the last day of my swap out period. I find this absolutely ridiculous. My phone has a factory fault, and i have the tests to prove it. I WANT A NEW REPLACEMENT HANDSET OR OTHERWISE THIS WILL BE ESCALATED FURTHER!
