No feedback on previous complaint,...useless!!!

Dear Vodacom, First I would like to say you are a bunch of *******, I want to cancel my contract and was advised by YOUR call centre to keep the airtime on the sim I need to do a sim swop and then cancel it. Then the alocated R2100 worth of airtime will be on the new sim to use as per prepaid when I want. Now I get to the Centurion Mall vodacom shop and they advise I will not get the airtime nor can they assist me to cancel the contract. How pathetic is Vodacom and the store that they cant assist in my query or cancellation. I have paid for this airtime and nowhere on your stupid contract does it state that I will loose the airtime should I cancel. This is a TopUp which is a prepaid contract. Pay R350 and get R350 value of airtime, WHAT GIVES YOU THE RIGHT TO TAKE IT FROM ME,…PLEASE REFUND ME THE R2100 AND CANCEL THE CONTRACT.
