Vodacom is a disgrace to the Cellular Networks

So I did an upgrade in October since my upgrade was due and because I got a call from a consultant saying that I am now able to upgrade. I get my bill today and see I am being billed for 2 handsets. my old handset and the new one I received. I called Vodacom to enquire about this because this has never happened. According to my Knowledge they make provision for you to upgrade 4 months in advance and that you only pay for the new upgrade. The person I did my upgrade with never mentioned anything about paying my old handset for the next 3 months. If I new that I wouldn't have done my upgrade I don't have money to pay for both. I am so disgusted with your *****ed ways this is not the first time I have issues with you guys. You refused to replace a 3month old phone that was under warranty that your technicians scratched on. Your company is a disgrace to the cellular community. Working in a financial institute myself , I know my rights and I know about client service and disclosure of all information to clients. Disgusted by this. If you do not resolve this I will take steps against you. Why offer me a upgrade if you don't disclose all the details?
