Brand new Phone software issues, Vodacom no Customer Service

I took out a new contract in the middle of September and received the device on the 18th of September, on the 4th of October I took it into Mall @Carnival Vodacom with software problems. They advised that the device would need to go to their repair center. I left the devices there and they sent it in. The last update I received from them was on the 9th stating it is in the assessment status. Since then I had to call to get updates. On the 14th I called them and they advised they had ordered parts for it and that it had arrived and they will finish installing the parts and test it, I should have it back in 2 days. NO feedback was given. I phoned them on the 16th to find out what was going on and the lady (I think Samantha) told me that they were battling to test the device and were waiting for an expert. On the 18th I phoned again and still no answer when I will get my phone back. I phoned today the 21st again and Samantha said that the manager is now testing my phone, when I asked if I could speak to him she advised he was not in. I phoned the Vodacom call center and they advised that apparently there are more parts now ordered for the phone and that they are still busy. I want a new phone. I am tired of these constant lies and disregard for customer service.
