unauthorised deduction

I app**** for a data contract online which included 2gb data and a device. They called me to confirm my details and the device was delivered. A few days later I noticed an amount of R1512.00 on my bill. I immediately contacted Vodacom via *** and they confirmed that they made a mistake by adding this amount. The amount was for the device but because it was a new contract and not an upgrade I was not supposed to pay.<br> <br> I kept on checking my bill and the amount was still there. I had to follow up and send emails because no one contacted me to explain why the amount was still reflecting. They reassured me that the amount will be removed from my account. A few days later when I checked my bill the amount was removed.<br> <br> Needless to say a month later my account was debited for R1512.00. I had to go through the whole process of contacting Vodacom and requesting them to refund me.<br> <br> I am still waiting for the outstanding amount to be credited to my account.
