BAD SERVICE BY VODACOM

After my 24 months contract with VODACOM i was sold a data and airtime package which was supposed to be effective on the 1st Nov that was on the 23rd Oct, but on the 1st Nov to my surprise the deal was incorrectly activated the package sold was not the package received,, i told them to cancel the entire contract on the 3rd November and they said the cancellation will be activated today ,However today surprise surprise when i call them to confirm i was told it was not cancelled and i have to wait another 30 days for my contract to be officially cancelled that means i cant even port my number to an alternative network, unless i do an immediate contract cancellation which gives them the an authority to block my number !
