Warranty ****

As I went into the store, the lady that helped me was on her phone most of the time and attendend to a call while I was sitting with her to send in my phone for repairs. Does not explain to me how this works or what is needed., My phone is STILL under waranty and when I called the repair centre, they said they are unable to repair my phone WHICH is STILL under waranty because there is damage at the back - first of all, what has the damage of a camera and the corner of my phone got to do with the wi-fi that does not want to connect to a network although it picks up the network? Second of all now my warrenty is voided because of the damage on the camera and the corner of my phone. They are charging heavy rates for data usage and when I went to investigate how to fix the problem, it says that the problem of the wi-fi not wanting to connect is a specific device problem of the huawei P 8 lite phone. Why do I have to pay for phones that have a problem in the first place? Either fix my phone that is still under warrenty or replace the damn thing. Useless service received from Vodacom and have been a customer for years!!!!!!!!!!!!!!!!!!
