Worst service ever experienced

I took in my wife's Samsung S4 for a screen repair on Saturday 19 September 2015 to the Samsung Centre in Roodepoort (Hendrik Potgieter).<br> The lady at the desk just basically booked the phone in and gave me some paperwork.<br> <br> I specifically requested that they repair in a weeks time as I had to drive from Rustenburg to Roodepoort just for this. <br> After I received no response I tried to phone the centre on the 26th of September probably 1000 times to no avail. Eventually I got hold of a Mrs Sophia Chitemere who told me there is something wrong and I need to provide them with proof of contract, which I then forwarded on to her. (Bear in mind this is the second time the same phone was repaired, no issues the first time).<br> She told me that they don't have stock and that it will be ordered. <br> We are now already on the 8th of October and I still try to phone and email the centre, I get no response.<br> <br> This is by far the worst service I ever experienced, unprofessional is an understatement!!!
