I wasn't told that I'll be paying for 2 phones

End October 2015, I visited Vodacom Dainfern branch, to enquire when my cell phone contract was expiring. I was told it has expired and I can take a new phone, which i did and ws very happy. To my Surprise few days lata when I checked the balance on my account, I noticed the amount ws different from what I was quoted. I then called Vodacom customer care and was told I'm paying for the old gadget and the new contract. I explained to them that this was not explained to me, as I would have waited if need be. I then went back to the branch and asked the branch manager to take the new phone back as I can't afford to pay for two phones. And most important, this was not explained to me. He told me I can't take back the phone as iv signed a contract . I ws very unhappy. Few days lata I called Vodacom customer care line again, explained wat happened. I ws told the branch wasn't suppose to do what they did and Vodacom will refund the amount already deducted. This never happened until today. I called again 2 days ago with no joy . And to top it all, end December they made two deductions of the already wrong statement. I really need help. Regards, Nokthula
