Incorrect information given

I have had DSTV with extra view for many years & have been a loyal customer with no return debits. On the 20 July I added an HD single view decorder for R699 onto my account. I was not advised to pay in & was told that it was too late for the july debit however it would run off in Aug. On 13th I got an sms to say my account was not paid, yet there was no return debits. I called and was told all was in order. 15th my mom advised the extra view was suspended. I called & a lady confirmed that you didnt debit my account for the HD decorder & it would run off on the 23Aug an amount of +-R1600. Today my extra view has been disconnected again. I called & spoke to Dumisani who then advises me I must pay in R792.22 & then my normal subcription of R1478 will go off on the 23. Im appauled at this, I should not be penalised due to imcompenties of staff. He also told me there was a note that I had to pay R69 when I connected the HD, this was not told to me & he also confirmed it was wrong. I have spent time on the phone at my cost due to this. <br> I want DSTV to accept the fact that they have erred & absorp the cost & start afresh with just charging me going forward as per R1478.
