Z5 Sony for Repairs since 23 Jan'16 already

On 23 Jan'16 I upgraded my Contract to a Sony Z5 Phone - Vodacom issued me with a Duo Simcard instead of a Nano Sim - I placed the Due SC in my phone and in the process damaged the phone, I drove to Vodaworld and handed it in for repair - which was not of my doing if Vodacom issued me in the first instance with the correct Sim. Since 23 January this phone is in the advanced repair center and all they tell me is \Awaiting Parts\" also they issued me with a quote for the repairs which I had to accept before any action were done. I have phoned & e-mailed 100 Times Customer Service, On Line and the Repair Center and everyone is just shunting me from pillar to post, I have now paid my first bill already on the new phone upgrade but still did not had the opportunity to even switch in on. This is the worst service I have seen in my life as you are just blocked off and no-one helps or allows you to discuss with management."
