DSTV has the worst service ever!

I upgraded last month from the R110 subscription to the R409 compact and was told I'm going to get a discount and pay R299 for three months, my subscription date is on the 2nd of each month I forgot to pay until it was disconnected and when I went to pay they told me that the system says I must pay r130 for it to be re-connected of which I did pay and indeed it was reconnected until they decided to disconnect it again today and when I called I was helped by a consultant named Wendy Njikazi and she told me the R130 I was told to pay was an error and she will remove the re-connection fee because it was an error form their side and I have to now pay R159 for them to reconnect of which I did and its still not on and when I called again I was now told I have to pay another R146 for it to re-connect and when I ask to speak to the manager they have been telling me the managers are in a meeting since morning and they don't know when they will be back, this is so unproffetional because I believe Multicoice uses the same system, why am I being told different things by different people and they cannot explain why, I have called them four tomes already now and they told me there is nothing they can do. I don't understand why I have to be penalized for their own system error, I was told to pay those amounts by them but I am the one who has to suffer because their system is showing them different amounts. is this fair?
