Damaged phone after repairs

I upgraded my handet to an iphone6 in Nov 2014.<br> On 26th Jan 2015 I handed the phone into the Century City Vodacom store for repairs, as the torch function of was not working.<br> I received all smes that the phone had been handed in and 2 days later another sms that the phone had been sent to JHB to the advanced repair centre.<br> 10 days later I received a phone call from a very rude and abrupt vodacom employee to tell me that the phones warranty had been removed due to physical damages (the phone was apparently bent) and that there was a replacement cost of R4800 for the unit !<br> <br> I was outraged ! <br> How could they just take my warranty away and what physical damages ?<br> I went back and checked my device evaluation form that was signed by myself and the vodacom consultant, which showed that there was no such damage.<br> I was then sent a photo of the phone, which is clearly bent !!<br> Since then, it has been a back and forth game between the escalations department, the repair centre and the Vodacom Century City Store.<br> Between the 3 of them, no one is willing to accept responsibility
