Whats going on with my account???

I phoned customer care last month to enquire about the balance showing due on the my vodacom app, the lady ensured me that the only outstanding amount at that stage was R271 odd rand. She also advised that the data i recieved was promotional and i will not be charged for it. I recieved another 10gigs this month? is this still promotional data for the new contract? The debit order has not yet been taken of my account, and i hope for you your sake that its not more than R599! Also, why havent you carried over my free minutes balance from the previous month?? Free minutes has always carried over, and I was not informed that it will not carry over on this package! Put back my free minutes and advise regarding this data added to my account again! I should've known its a bad idea to take a contract with you again, as if I havent learned my lesson in the 10+ years i've been a contract customer!
