Charging me for in warranty repair

<p>I have been given a quote to be charged for an in warranty repair, after specifying that I have already brought the phone for repairs FOUR times. I even requested that I would prefer a new phone to compensate for the hassles over the past 2 years. Now they tell me that the phones warranty is void because of a crack on back cover! When I handed the phone in there was no crack! It was not even stated on the job card under comments of phone when I booked it in! Very disappointed with service. The turnaround time(7day)is over today and no feedback yet. Never choose Vodacom. Terrible after sales! </p>
