Complete fail!

<p>In June this year I approached a Vodacom branch in Westgate and entered into a cellphone contract arrangement allowing me to receive R200 airtime and 500 megs, in return, i ought to pay R199 per month. To my surprise, i found that i had been placed on a different package with gave me uncapped airtime and i was informed that i had to pay for what i use. I reported this mishap immediately at the branch upon which i was told that the error was not on their side but with their 'trade partner' whom i had no privity with. I was promissed that the matter would be followed up but it never happened. i am now being threatend to pay R15000 or else legal processes would fail. Can someone please assist!</p>
