Incorrect billing after DPP explora R799 package

I got my explora through the DPP R799 pm option on the 26th of december. I have phoned DSTV to activate it and they did. Beginning of Februarie i phone again because i noticed that my package has not been change to R799. The guy said it is fixed. The a couple of days later another lady phone and said that my package is still not on R799. She said she could not do it because I have to be home to check the messages on my explora when she change it. She said she will call after 16:00 when i am home and never did. I then noticed that my amount due is R1024 rand. After a huge fight dstv said the have found the issue and a journal will be added to deduct about R160 of my acount because their fault. I have now checked my account again online and noticed that the journal was added to my account and amount due is now R1200. First of all the incompetence of the DSTV helpdesk is shocking. I need a senior person to fix this asap otherwise I will go to the bank and sign a stop order for the amount until this is sorted out. If this is not sorted out in the next day a will go the papers/internet on this. THIS IS UTTERLEY SHOCKING. Cannot believe tthis **** service!!!
