New contract - incompetence

I ordered my new phone online on a contract and ported my simcard from MTN to Vodacom. When I received my phone I inserted the simcard and left it off for 5 hours to activate as told by Vodacom. When I turned on the phone it was not my number which I ported. They were closed on Friday when I had to speak to the aftersales department so I called back Saturday morning (7 Feb). The lady in aftersales 'ordered' a new simcard and said I would receive it by Monday. It is now Monday afternoon and I am still waiting. After numerous online conversations and phone calls to them, they still have not assisted me. On the last call I was now really upset and told them I want it today and all they can say is that it will take another 5 working days...OMW this is really bad service as it should've been delivered with my phone in the first place. Why go through all the trouble then of porting it????? So much for changing networks and thinking they will be a better option.
