WHY UPGRADE WHEN VODACOM SAYS YOU ELIGIBLE!!!!!!!!

<p>I called to enquire about charges on my account this morning that make no sence. I upgrade at the end of June to a new contract - I see that I have 2 handset installments - when I queried why, I was told that 1 is for the old handset - that I will be charged for the next 3 months......SO WHAT IS THE POINT OF UPGRADING THEN WHEN VODACOM SAYS YOU ARE ELIGIBLE IF YOU STILL GOING TO PAY FOR THE OLD HANDSET!! Why are we as customers not informed of this by the UPGRADE DEPARTMENT when we upgrade?? The nano sim was also not included in my upgrade - when i contacted VODACOM they said I can purchase one at the local store and I need to send through the details and my account would be credited......(Iemailed everything through as requested) but there is nothing on my account</p>
