shocking service

I have sent my P8 Huawei Lite in for a software problem over two weeks ago. This problem is the second time in six months I am sending it in. The agent at the vodacom shop says there is a known issue with the P8. After two weeks not hearing back from them I finally get in touch only to find out the wanting to charge me to fix it, as there is a crack on teh screen. when I mention that I am not talking about the crack but a software problem they rudely and sarcastically reply that there is no software problem that causes a crack on the screen. Hello read the job description it states that I am having a software problem where it does not connect to wifi unless turned on and off. I am disgusted with there shere lack of respect for customers and even contacting huewei about this problem and getting it sorted correctly.
