Cellphone Home Choice

I bought a Hisense E60 cellphone from Home choice and after a few months the phone's screen just went dark. there is no picture although you can hear sound. I contacted Home Choice in this regard and after 3 weeks of continuous calls the problem was still not resolved. I was told that a courier from Hisense will collect the phone , which never happened. I contacted Hisense and was informed that Home Choice must lodge a call at Hisense before they can assist me. Please help as no one at Home Choice is willing to solve the problem. Can some one help please!!!!!
