Bad customer service at Cell Zone

I am disgusted in the service I received from Cell Zone. Had a new LCD put into my iPhone a week and a half ago. Now the LCD has gone off. When I took it back to him, he tells me it’s not under warranty and I must pay for a new LCD. He failed to mention that there is no guarantee or warranty on his goods supp**** or installed the first time. All repairs is for the customers own cost. He refuses to take responsibility for any faulty goods supp**** by him. Please be aware of Cell Zone East Point Shopping Centre. ********** 870, ********** 399 or ********** 140.
