fals selling

I had I contact with vodacom . I upgrade to a sony xperia z 1 compact. I bought the phone especially because they said it is water resistant. This was last year September. By desember last year I handed the phone in at vodacom caledon because I try to take pictures under water and then the screen when dead. By january 2015 I still haven't heard anything. The phone got lost while they had it. By March they send it back to caledon branch and said that it is damage so they can't fixed it. Im still paying every month and im still without a phone. Im disappointed in sony and vodacom for the way they treated me as well as not replacing the phone. They cancel the warenty on the within a day after I handed it in. Up to now no one has ever contact me or done anything I had to call and find out what they gona do. Why sell I water resistant phone if you can't use it why misleading the customer. This it not only bad service for vodacom but sony too. I am not happy at all. And I want a new phone but now they told me I have to wait till I can upgrade but im paying for something I dont have or use. BAD BAD BAD
