SONY and Vodacom lies

i have purchased a Sony Xperia Z2 a few months ago. The phone recently came into contact with water and switched off. All ports were tightly sealed and only the camera portion of the phone touched water. When i advised Vodacom they advised that the phone is water-resistant and not waterproof. Please follow this link as proof that the phone is waterproof [URL Removed] I was advised that vodacoms tests said theres not manufacturer faults and that warranty will not cover it and that i would have to pay for repairs? Why do i pay? Sony obviously made a **** product and vodacom is trying to put the blame on the consumer.
