'Repairs' damaged device further

I took out a new contract with Vodacom at the end of June (not even three months ago, against my better judgement, after having prepaid bliss for years ) The phone is a Sony XPeria Z3 compact.<br> <br> Here's a breakdown of what's happened in the 3 months since I've had the phone:<br> <br> 1 - The screen got a random purple spot on the screen shortly after I got it (this is a know Sony fault)<br> 2 - The screen cracked due to the weak spot on the screen when falling off my car seat<br> 3 - Repairs refused to take care of this under warranty, so I had to pay to get the screen fixed<br> 4 - Phone is returned to me with a faulty phone microphone and speaker<br> 5- Phone gets booked in again<br> 6 - Phone is returned to me with a crackling noise in the upper half of the screen when pressed<br> 7 - Phone gets booked in AGAIN.<br> <br> Not only was my new phone returned to me in successively WORSE conditions, but the sales consultant at the Vodacom Data Store in Cavendish was completely unsympathetic and unapologetic. I've experienced nothing but bad customer service and *********** repairs in the three months that I've had to deal with Vodacom. I've demanded they supply me with a new device.<br> <br> STAY PREPAID! It's not worth it.
