Multichoice cycle

We phone multichoice 3September to put one of our decoders off for 2mnths. Every night when we want to watch tv our pvr is of. We phone them 4 to 6 time then they tell us its IT problem we must wait 2hrs, after 2hrs all is going off again. Eventually i got some woman who sorted it out in 2min and everthing was on. Month end i ask for decoder to be put on again, then the lady told me i own them a mnths money, i phone to late to cancel the container it mus be before 28th of month before next sycil starts.....what the debit order go through on the 28th how can the sicle get stopped then. She had lots of stories and refuse to put the decorder on. If you ask for statement to see that you pay for, you get told to go and find it on there site. We went and it was 2mnths ago statement. That dont help me at all. I must say i did do this previously when my mom came and vissit me and then the cycle can get stopped. Im really not impress with the service we get fom dstv. I ask the woman to speak to her supervisor, she said there is no supervisor on herfloor i must hold she will go and look for one...!!!! What is that the way you speek to your customer????
