Please Upgrade but still pay for old handset

Good day,<br> I went to upgrade at the lovely Vodacom shop here in Bloemfontein, after receiving an sms that I am ready to upgrade.<br> I chose my new package and I was really happy, until my bill was almost R100 more than it should be.<br> Turns out, even AFTER getting an SMS that you are ready for an upgrade, you still have to pay for your old handset until the ENTIRE 24 months are up.<br> No one informed me of this... If they did inform me, I wouldn't have upgraded.<br> I have been told getting this money as a credit is a lost cause, unless I go to the branch and ask the person who made the mistake of not telling me to pay me the money back.<br> There is no way, someone will give away their hard earned cash for something as silly as this.<br> Since I work in the same industry, I know that previous handset has LOOOOONG been paid off.<br> Vodacom will not see me again and I will now choose MTN or Cell C for all my accounts, business and personal.
