Paying for data i have not received and other issues

<p>Last year a consultant - Calvin Pillay from Vodacom Business convinced me to subscribe to 2GB monthly topup with a small modem - the SIM never worked and we aggreed that the device was being fetched and the contract refunded. the device and SIM Card was fetched but i am still paying every month for this - i have sent an e-mail regarding this to 2 people but no response. I have also visited the store again at Menlyn Park where i did an upgrade on my business contract last year NOvember and at the time the contract offered and extra 10GIG once off which i never received - i was asked to rate the service, but still have had no feedback on the Data - and this by speaking to the manager who promised to contact me. so i really advise everybody to think twice before doing business with Vodacom - if not resolved soon - i will take this to the consumer council as well as post all over facebook etc ...</p>
