Sony Xperia Z3...FAULTY!!!

Got my 'upgrade' from Vodacom mid December 2014. <br> Feb discovered the front camera was faulty. <br> Handed phone in to Vodacom 23/02/15. I was told that the longest I should expect to wait would be 14 days.<br> No coms from either Vodacom or Sony during the time they had my phone.<br> 24/03/15, received an email saying that Sony have replaced the board of the phone (after having assured me that Sony don't 'refurbish' phones).<br> Firstly Vodacom said that they did not have the phone, eventually tracked it down after showing them the email.<br> I requested that they set the phone up for me, which took almost the entire day.<br> Then there was difficulty inserting the sim. <br> After rebooting the phone it was unable to receive signal. <br> I tried making a call - the phone froze and switched off.<br> I was told that the phone needed to be sent back up to JHB. It is now the 1st of April 2015, still no feedback...only that the phone is currently in the assessment process!<br> The phone was sent in for a camera fault, it is now in for a signal fault - my phone has clearly been replaced by another faulty device, this is unacceptable!! Still waiting to hear back from Sony Cust care, left several msgs. Very unhappy customer :(
