Wrong Billing & Confused Consultants

Can someone who actually handles accounts sort out my account, hopefully they studied accounting at least because your consultants clearly don't know what's going on. I'm tired of explaining one thing over and over again. My due date is the 26th firstly, now someone has changed it to the 10th. On the 26th of July I was charged R789 for the month beginning the 26 August, August came and I didn't pay. DSTV was cut off and for the week it was on, a charge of R178.16 was allocated. Now 1st problem, the R789 for a month's viewing was not reversed and it's still sitting there. On the 5th of September I downgraded to Compact and the charge for the rest of the month, plus access fee and the R178.16 came to R494 as was communicated. I paid R500 for the services to be switched on. Now the next month's subscription from 26th September was also charged of R365 and access fee of R85. On the 9th September I upgraded again to premium, so the second amount that should be reversed is the R365 for the next month's viewing. I'm told a difference for the current month is R246, I pay R250. Now all things being normal, my account should have a charge R874 give or take due on the 26th of September for the next month. It doesn't, instead it says R1001.68. Furthermore an additional R5.48 access fee has been charged, like for what???? Isn't access fee the same on all packages???? Don't get me started on consultants telling me there is an outstanding balance of over R400, from where??? Is Premium R1300 now, nevermind how many days I was on compact and the days it was off. What **************** is going on there????
