Phone not repaired!!

I upgraded in Feb 2015 to an Experia Z3 Compact, but after a month the camera wasn't focusing anymore. I decided to hand it in to the local Vodacom Chatz(Louis Trichardt) store to be sent to the repair centre in Polokwane(job no. ***0) I received it on Monday after waiting more than 3 weeks. My phone was back to factory standard(all my downloaded apps removed etc.) but the camera is still not working! The phone I was using for the last 3 weeks does not work all the time, so I am really struggling! I can't wait another 3 weeks using a problem phone. I logged on to the Vodacom website to complain by e-mail just to find that nothing happens when I try to send it! When I phone Customer Care, I'm on hold for ages. I eventually put in a call back, but guess what? 2 Days later and no call back! So now I am forced to put my complaint on Hello Peter. I feel this is really bad service! The Z3 is only 4 months old and should not be giving problems yet. I have been a loyal Vodacom customer for MANY years, but this is unacceptable! I am tired of waiting, so I demand a new phone or at least a loan phone asap until mine is repaired.
