Hisense fail to manufacture functioning cellphones

I went to go buy a hisense (HS-U961) phone in June 2015 at EDGARS EASTGATE. Four months later the phone started to freeze and the speaker stopped working properly, so i took it back to Edgars.<br> I continued to make the run around to Edgars to go ask about my phone, NOTHING! <br> Finally after 4 months without my phone i got it in January 2016, this was with the help of Nandi the EASTGATE EDGARS DEPARTMENT STORE MANAGER, who solved my case within just a few hours. Its February now and the phone is freezing again, worse now and needs to be switched on and off before i can use the apps on the phone. <br> I WANT MY MONEY BACK BECAUSE THIS PHONE BELONGS IN THE DUSTBIN NOW!!!
