Poor and disgusting customer service

I made 2 payment at the beggining of this month R400 and R170, dstv has been disconnected my viewing every second day since the beggining of this month saying thay there is an outstanding amount that i should pay even though i know very well that i have paid. I sent them an email lastweek and they told me to pay an additional R115 to bring my account up to date of which i did and 2 days later they again blocked my viewing just as they have been doing ever since this month started. At some point they told me that I have a second pvr decoder that i know nothing about. As it is my channels are still blocked and no one has bothered to call me back after they promised to get their team leader back since yesterday. I sent an email to DSTV help and I have had no response since yesterday. ENQUIRY REFERENCE NUMBER : ‪***4‬
