Worst service ever

DSTV has given me a hard time. At first i called in to cancel my decoder as it was burned out so i got a new decoder. I phoned in to connect the new decoder and told them that the other one burned and i would like to continue on the new one only. They made me pay 2 decoders for months and didn't canceled the burned one. I phoned in and fix that again and changed my package but now they did change my package and made me pay extra every month. The people in the contact center don't do they job right and just expecting me to pay for their mess. I am so tired of it. In the beginning i paid just to keep the peace but now i am fed up. They keep taking my money for no reason. They need to do a better job and pay attention
