Bad service from Cell C

<p>I upgraded my contract two months ago (April 2016) and two weeks ago i noticed vertical lines on the front screen of the Huawei P7 .I phoned the customer care line the same afternoon and they asked whether the phone fell.</p> <p>I told them that it did NOT fall and they send a courier to fetch the phone a week later.During last week i was told that they quoted me R2200 for a replacement phone as the LCD is broken.How can the LCD be broken if my phone was not dropped and they can see the condition that the phone is in.This phone is still brand new.</p> <p>On Friday i sent a email to the repair centre to esculate without any response.</p>
