Sony Xperia Water Proof, False Advertising

I have a Xperia Z3 Contact that has been at the SSS Cellular Johannesburg repair centre as requested by Sony Head Office, device was delivered 1st of April 2015. I called them 2 weeks later to find out my device was booked out of warrenty, I said the device is 3 days old and cannot be out of warranty, they updated the system and then booked the device in warrenty, a week later I called again only to found that the device is Beyond Economical Repair. I then emailed ***mobile, only to find out if the device is BER then the warrenty is void. This is clearly a factory fault as clearly many sony xperia Z3 users expereice the same issue with this handset as well as the same **** service from both Sony and SSS Cellular. My device is still at the SSS Cellular repair centre, it has been 2 Months passed now, still no reply, complaint was logged on hellopeter, received a response from Melisa Warren stating she will investigate. It has been a month I requested feedback received no response from her. Does anyone know the CEO of Sony aswellas SSS Cellulars email address or contact details as I will not stop untill this deviceisrepaired or replaced as all portswerefuly close
