Account incorrect

After several calls and people I spoke to my account is incorrect which I tried to prevent to follow up twice on a premature cancellation I have paid and done on my 072.. Number.. Now my account is over R1200 which is not correct and the person (Iada) I spoke to at customer care she told me it caused confusion and I did not paid my account the 1st..I told her previously Vodacom customer care informed me that if the 1st is over a weekend or a holiday the debit order will be going off on the next working day.. So ja my debit order went off but according to this vodacom consultant I am fault due to the day my account was paid.. This is not acceptable my account is not correct norvthe factvthat I was told I confused them due to the fact I did a premature cancellation.. What happened to customer care/service and the fact that we need to rate the service.. I will not give them a rating at all because I dont get service from vodacom nor am I a happy customer
