I am a customer of Vodacom

I am a customer of Vodacom for several years. My latest experience with the Vodacom was very disappointing. My daughter was due for upgrade and we opted to take an upgrade from East Rand mall as we enquired about what package where available the staff when into the computer with the words that I am in arrears with my account which I query but show on the system no payment was received leaving the store I phoned Vodacom and ask what is wrong as I got prove that I paid, the long and the short it come that the didn't update the payment. How is it possible that a big company takes days to update their system and then they transfer me to some account lady and was shocked what she explained. Vodacom you thing you this big company and untouchable ask Dischem what happened when South Africa closes the purse the future is still there greetings
