Getting no where and rude call center agends

We cancel our dstv on the 8 aug 2017 which they told us we dont have to cancel cause if the account is not paid it gets switch off automatic cause its a month to month contract. Dstv never switch it off and they let it run for extra 7 days and now they want to charge us R209 cause the idiots never switch it off and they have put their laywers on us and they keep bothering us. Its also useless to phone cause the lawyers dont hve a clue whats going on and dstv call center agends does not want to listen do what i have to say they are rude the lady told me 3 times to keep quiet cause she wants to tell her story first.. i gotten so mad i put the phone down really is this the way you train your call center to speak to customers.. stop bothering us if the fault was on your side. Dstv your the worse really..
