Shocking repairs department

I took my phone in for a simple repair at the Vodacom repair shop in Somerset west on 17 March. They said that it will take 2 weeks maximum for me to get my phone back. Tomorrow will be one month and no phone yet. I have phoned them a dozen times to follow up on where my phone is. And every time l get told that the repair department is busy or on another call. And it does not help leaving messages, the never phone back. I have been lucky enough to speak to someone twice about my phone now and all I get is that the phone is still in Joburg and that they are having trouble with loading software. And that they will phone me when they know what is going on and when they receive my phone. I am still waiting for feedback from them. If I don't call them every day, no one even bothers to do anything about it. There has been no progress regarding my phone these last 2 weeks and no one can tell me when I can get my phone back. The service has just been horrific!!
