MULTICHOICE IS PATHETIC

Hi this is the 3th consecutive month that im experience problems with Multichoice. Last month i requested to change my package from premium to compact and the consultant told me to phone again before the end of june in order to do that and the price for compact will be R409.00. I phoned them on Tuesday 29 June and another consultant informed me that she downgraded my package to compact which will be R409.00 and R135.00 for the use of my pvr functions, which i agreed upon. On Wednesday 30 June i made a follow up call and another consultant told me i must pay R799 which i didnt understand. The previous day i was told R409.00 +R135.00 and the very next day its R799 which i couldn't understand. He informed me of a R255.00 outstanding that i dont know of. What i want to know is how and why on earth does Multichoice add amounts to my account as the please. Im totally disgusted and dissapointed by tge way the are ripping me off. Different consultants with different amounts. Im fed up with multichoice coz month after month i have to complain about the same thing. Im not wiling to pay the R255.00 that only they know about. Im only aware of the R409.00 +R135.00 (R544.00). Can Multichoice sort out their mess and stop being ****** by ripping of customers.I also asked them a long time ago to cancel/disconnect the other decoder which im not using for the past 5 years and the also didn't do that.
