DSTV charges for services that customers did not consent to

DSTV erroneously reconnected service and began charging me for services I did not ask for. There is no urgency from them to rectify their error. They refuse to close the account and continually need to 'investigate'. I did not expect that I would need to explain to an organisation like DSTV that (i) it is ******* to prey on unsuspecting former customers by reconnecting services without their consent and charging them for said unwanted services; and (ii) having made such an error, it should be rectified with urgency. This is completely unbelievable!
