MISLEADING PEOPLE AND DONT WANT TO HELP

i have a sony z 3 that I just bought ,It was actually a day old when I put it in a 500 mils of water at home in a jug.I dipped it in and took it out but noticed that it had started to freeze,to my suprise the phone is not by means resistant to water.I phoned sony mobile and they told me to send it to sss cellular who has told me that the phone is beyond economic repairs.I phoned sony about this and they is nothing they can do i must just accept that my phone is damaged.I spoke to Mohammed Yehia who was assisting me with the complaint and he told me he cant even escalete my complaint because it not valid,I asked him how so bcz I dipped my phone in water with all the ports closed .I am frustrated I asked him if theres no cutomer services and how do they deal with such complaints as all my ports were closed He kept on telling me to accept that my phone is damaged.
