UTTERLY PATHETIC SERVICE!!!!

I have just sent my Sony Z 3 in for repair for a THIRD time in as many months. First repair was a month and three days after I recieved the phone. The battery swole and cracked the back cover, and the phone kept resetting. Despite it being a manufacturer fault I still had to pay for the repairs (?R500). On top of this I had to wait more than a month for the phone. A week later the phone started freezing up and resetting again. I then took the phone to Vodaworld hoping I would get better service being HQ. I collected the phone this afternoon and switched it on on my way back just to find the exact same problem again. According to the technicians report there is no problem with the phone...makes me wonder if any repair did take place. I went straight to the Menlyn branch to hand the phone in for the third time,and despite asking to replace the phone I was blatantly shrugged of and the phone sent away for more repairs. In the mean time I am paying Vodacom a pretty penny every month for a phone I dont even have!!! Ive been a client for more than a decade and this is the service I get for my R 2000 a month...PATHETIC!!!!
