Wrong information

I went to a vodacom store last month in Clearwater mall to inquire about about my upgrade on one of my contacts, the consultant told me i was due for unpgrade, but however vodacom removed my payment plan, this is after i have never missed any vodacom payments since the inception of my contract, so i could not upgrade as i wanted to/ the consulant then told me that i had finished paying off the device on my contract end of November, which means that the debit order that will go off end of December will not include the payment of my Note 3 because it is paid off already. To my surprise vodacom debit the full R1400 on the 3rd, when i called the customer care service, the lady i spoke to says on her systems it shoes 24 months of me paying for my device, but that is not what i was told when i went to vodacom last month, i was told that i will only be oaying the contract amount until the contract finishes. this is *********** service i received from vodaom, especially for the amount i am paying on a monthly basis i expect straight information from either the call center or their stores.
