Pathetic service - Breach of Contract

I am a highly dissatisfied customer of the Vodacom branch in Somerset Mall at the Pick n Pay side - the managers name is Jacques, number ********** . Since I have signed my upgraded contract with Vodacom shop at Somerset Mall, the issues is just not going away - the next step for me will be to go to small claims court as it seems like Vodacom cannot sort out my incorrect account. Firstly, when I got my new phone I insisted on a closed contract and a top up account and signed for R597.50 every month that will be deducted by debit order - this was unfortunately not the case the wrong persons details was loaded onto my contract for a tablet - after this very high amounts of data usage was deducted from my account. After the contract was "corrected" they kept on charging me the incorrect invoice and double charge me for my handset. I called the Call Centre and visited the brand numerous times, my mom has also been to the shop to try to sort out the incorrect contract with Jacques. I do believe I have rights as a customer because this is breach of contract from Vodacom. My next step will be to publish the bad service in the media and finally go the small claims court.
