Pathetic...****ed of customer

my husband has had his xperia z3 for 3 months and has dropped it not once we work up one morning to find the screen had cracked internally vodacom said it would be R4500 to fix it but that's half of the amount of the phone i then decided to google it and i read that a crack like that should be under warranty but neither sony nor Vodacom know how to fix this matter instead want me to pay for a faulty phone while my husband sits phoneless and still pays for the phone. i have always been an iphone fan and my husband convinced me to move to sony now that we have this issue we are told to call SSS Cellular which i have been doing for the past two day straight and no body answers the phone and when i dial again the line is busy its sad how sony has one repair store in the entire country what nonsense is that i am highly disappointed in sony and i want this to be rectified immediately...
