bad customer service

I upgraded the number ********** with vodacom, I actually wanted a mini tab. I asked the call centre agent about the size of the device she was recommending. She told me it was big, but after delivery on Friday I realised that she had upgraded me from a Galaxy Tab to a phone. This even came without a sim card, are they trying to say I should buy my own sim? The second number is ********** , which I was advised earlier in the year by Vodacom to change to a cheaper package but now I do not see the difference. Instead I'm paying more on this package with data finishing off every month.
