Poor service & empty promises !!

I got my new phone on the 23rd Dec 2015 through an upgrade - Iphone 6s - used it for approximately a week and started to have problems with the ear piece. Called in on the 31st Dec 2015 to notify the upgrades team but noone was available so i decided to go in on the 4th Jan 2016 but to my disappointment I was 15 minutes too early and there were 3 agents at front desk who told me they cannot assist because they only open at 8am. So i decided to leave so i could get to work on time. Came back the same day at around 16:30, was assisted by Nicolene at front desk who advised that no managers were around to make a call to swap the phone for a new one. She promised to get back to me on Tuesday and i waited the entire day with no feedback, i tried calling her a few times to no avail. Eventually on Wednesday I went at around 10am and dropped off the phone was told that the phone need to go in for repairs and once again was promised speedy turnaround times with the inspection to finalise the matter. I called her today and she advises that theres nothing she can do and I have to wait since its handled by a different department. I just renewed my contract and this is the service I get<br>
