Very dissatisfied, disappointed, poor service

I upgraded my HD decor to an explorer, l was advised to to do a debit which l agreed upon first month of January everything went well they debited R644 then in February the challenges started they wanted to deduct +-R1400 l called in to enquire no one could explain what was going on butl was advised to pay R656 which l did but less than a week the DSTV had been disconnected am making calls more than an hour on the phone but staff can't even help me with this issue so who do l turn to in this situation. Am spending on airtime to call for solutions but it seems like no one cares about the customer as long as they got their money. They don't even understand the distress they are putting us through. Can someone attend to my complain if the management has to be involved please do so.. I can't accept this type of service. Am paying you so why can't you deliver the services. Maybe the solution is to cancel since they don't value me as customer
