Vodacom trying to Save a Buck - Warranty Shocker!!

I have had Sony Z1 for roughly the past 1,5 years with no issues whatsoever up until now. The phone was taken on upgrade on a contract which I have held with Vodacom for the last +-8 years. The phone has been used as an average person would and has incurred the usual everyday nicks and scratches of daily use. On one morning in particular, the phone was dead and did not want to switch back on and on charge it only responded by the notification light flashing red but still not coming on. I then booked it into Cresta Repair Centre. Job No:***8 - Upon picking up the phone on the 04/01/2016, I was told that the phone was irreparable and the report said that the phone is \deemed physically damaged due to abuse, Handset is B.E.R - Physical damage caused to handset\". I have asked Vodacom upon escalating this case to provide a full in depth report is provided to me proving how these scratches have directly resulted in the unit failure and what the fault actually is as these minor scratches occurred months before the phone actually failed which they and Sony have failed to provide. This is ********** treatment to a customer with 12 year history with the network. I AM DONE WITH VODACOM!!!"
