Shocking service and a *******!

In the year 2015, my account kept creeping up from R750pm to R4000pm, which is totally ridiculous because I am a single marketer, using only email, and facebook for short periods of the day, as I'm on the road most of the time. I asked telephonically for an investigation into these amounts, and got absolutely no response from Autopage! Eventually frustrated, I found out when my account was up for renewal so that I could cancel. I was told September, but was told that I had to pay the settlement - Nokuthiwa ref: 13/11 quoted me R1567.79 - which I agreed to, and they sent me the forms on email. I signed them, and made the payment at Nedbank on 16 October and faxed through. But they continued to debit my account at the end of October. I called and was told the settlement amount was incorrect! I told them that it's not my fault that they gave me the incorrect amount and this must be sorted out. I blocked them from my Nedbank. Still they managed to debit my account at the end of DEC for R569/something! Now they've told me telephonically to pay a further R3664.92 to close the account, and have sent me the settlement form which is for R569.00 - so what is this? I held on for 30mi
