Wrong Billing

In October I upgraded, at the end of the month I contacted them and said that my balance don't seem right. They said I should wait for the Invoice. On the 15 November I received the invoice and contacted them , I indicated to them that they double charged me for my handset. I logged the incident, 2 weeks later my wife asked me if they fixed the bill? I contacted them a few times , being very frustrated as this is not the first time I struggle with them and i want to pay my bill before the end of the month. I told them that we wanted to pay, other wise they are going to list us on ITC that we are paying late, this after there invoice is incorrect. They apologized and gave me the correct amount over the Phone and said that they will credit me the following month and that I should not stress about my ITC. The following Monday I went to the bank to get an over draft as I am busy in the process of buying a house. The bank told me that I did not pay Vodacom for the month of October of which I did, Exactly what I was concerned about. At the banks office I contacted Vodacom, they confirmed that I did not owe them any money and that I did not pay late. They sent a letter and the bank helped me two days later. So this affected my credit profile and made me feel like an idiot. And it made it seam that I don't pay my accounts. This also cost me hours on the phone of which was Vodacom's Admin problems. This month exactly the same thing happened they double charged me once again and sent me wrong invoice. I phoned them, still waiting for them to sort this out. I am a subscriber on ITC , of which I can see my credit record any time. In August they said I paid 30 days late, of which is untrue. I pay my bill every month on the clock. Once again there Admin problem affecting my credit Profile of which I am very proud, and worked hard to maintain. I feel that I am within my right to start taking legal action against Vodacom for damaging my credit profile, of which is the one thing in life which closes doors for you if not maintained. And this could affect my process of buying a property. Every month I Pay my bill on time , never miss a payment. I must contact them several times , which takes several hours of my time because of there Admin issues. I pay for a service , but I am effective negatively. Maybe if I was not paying my account or in arears I could understand. I am tired of this bad service of which I am paying for every month and being negatively affected. I am going to take legal steps, because big companies like this don't care about there customers at all. I am going to all sites and Media and complain about this. ITC is not a switch of which someone can say sorry and it disappears. Its something that takes time to build up. And if my house that i am currently bussy purchasing is affected, ??
